Answer:

[tex]m\angle 1=95^{\circ}[/tex]

Step-by-step explanation:

If we drew an auxiliary line parallel to line [tex]p[/tex] and line [tex]q[/tex] that intersects the vertex of [tex]\angle 1[/tex], we would form three angles, one of them being

The largest of these angles corresponds with the angle marked as [tex]148^{\circ}[/tex].

The angle on the bottom right corresponds with the angle next to the one marked as [tex]63^{\circ}[/tex]. Therefore, its measure is [tex]180-63=117^{\circ}[/tex].

Since there are [tex]360^{\circ}[/tex] in a circle, we can now write the following equation:

[tex]m\angle 1+117+148=360,\\m\angle 1=\fbox{$95^{\circ}\checkmark$}[/tex].

Answer:

95

Step-by-step explanation:

The way SkiffMacKinaw did this problem is the way it should be done. There is another way of doing it by extending both arms of <1 until they intersect p and q and solve the triangle hanging from p.

You then find the the angles of the triangle. The vertex angle is the supplement to <1.

This method works but it is not nearly as elegant as the original answer. This is one of the best awarded Brainliests I've seen lately.

Answer:

[tex]A \cup C=\left \{ \text{q, s, u, v, w, x, y, z} \right \}[/tex]

Step-by-step explanation:

Given: [tex]\text{U}=\left \{\text{q, r, s, t, u, v, w, x, y, z} \right \}[/tex], [tex]\text{A}=\left \{\text{q, s, u, w, y} \right \}[/tex], [tex]\text{B}=\left \{\text{q, s, y, z} \right \}[/tex],

[tex]\text{C}=\left \{\text{v, w, x, y, z} \right \}[/tex].

To find: The elements in the set [tex]A \cup C[/tex].

Solution:

We have,

[tex]\text{U}=\left \{\text{q, r, s, t, u, v, w, x, y, z} \right \}[/tex]

[tex]\text{A}=\left \{\text{q, s, u, w, y} \right \}[/tex]

[tex]\text{B}=\left \{\text{q, s, y, z} \right \}[/tex]

[tex]\text{C}=\left \{\text{v, w, x, y, z} \right \}[/tex]

Now, [tex]A \cup C[/tex] will contain all the elements in the set [tex]A[/tex] and all the elements in set [tex]C[/tex].

So, [tex]A \cup C=\left \{ \text{q, s, u, v, w, x, y, z} \right \}[/tex].

Hence, [tex]A \cup C=\left \{ \text{q, s, u, v, w, x, y, z} \right \}[/tex].

Answer:

0.2 miles

Step-by-step explanation:

From the above question:

2 miles = 10 minutes

Hence:

10 minutes = 2 miles

1 minute = x miles

Cross Multiply

10 minutes × x miles = 2 miles × 1 minute

x miles = 2 miles × 1 minute/10 minutes

x miles = 0.2 mile

Hence in 1 minute it would take her 0.2 miles

Step-by-step explanation:

Let's solve your equation step-by-step.

6=3x+3

Step 1: Flip the equation.

3x+3=6

Step 2: Subtract 3 from both sides.

3x+3−3=6−3

3x=3

Step 3 divide 3/3 = 1

x=1

Answer:

The system will be

f(x)=4.55x+40

g(x)=5.75x+10

Both company 1 and 2 charge $153.75 for cleaning 25 garment

Step-by-step explanation:

Equation 1

[tex]\frac{85.50-62.75}{10-5} =\frac{22.75}{5}=4.55[/tex]

y-62.75=4.55(x-5)

y-62.75=4.55x-22.75

c(n)=4.55x + 40

Equation 2

[tex]\frac{67.50-38.75}{10-5}=\frac{28.75}{5}=5.75[/tex]

y-38.75=5.75(x-5)

y-38.75=5.75x-28.75

c(n)=5.25x + 10

The system will be

f(x)=4.55x+40

g(x)=5.75x+10

30=1.2x

x=25

f(x) when x=25

f(x)=4.55x+40

f(25)=4.55(25)+40

f(25)=113.75+40

f(25)=153.75

Both company 1 and 2 charge $153.75 for cleaning 25 garments.

Answer:

7x=42°

8x=48°

Step-by-step explanation:

Sum of all interior angles in a triangle=180°

90+8x+7x=180

90+15x=180

15x=180-90

15x=90

x=90/15

x=6

The measure of each acute angle is 42° and 48°.

If an angle is less than 90 degrees, then it is called an Acute angle. Acute angles measure less than 90 degrees. Right angles measure 90 degrees. Obtuse angles measure more than 90 degrees.

Given there is a right triangle. since it's a right triangle angle one angle will always be 90 degrees.

Since the sum of all angles of any triangle is 180 degrees thus,

7x + 8x + 90 = 180

15x = 90

x  = 6

since each acute angles were 7x and 8x

hence those angles would be 42 and 48 degrees.

therefore, Each acute angle is 42° and 48° in size.

Answer:

B. 90

Step-by-step explanation:

Because if the building is 60 and the statue is 1.5x the height of the building then it would be 60 x 1.5 = 90

Answer:

The answer is B because 60 x 1.5 = 90

and if you do 90 ÷ 1.5 you will get 60

Step-by-step explanation:

Angle FAB = Angle BHC = 48° (Z-angles)

By Exterior Angle Theorem,

Angle ABC = Angle BHC + Angle ECB.

=> Angle ABC = 48° + 18° = 66°.

Answer:

The height of the hot air balloon is 1514.54 feet approximately.

Step-by-step explanation:

Consider the provided information.

The angle of elevation from the top of a 95-foot tall building to a hot air balloon in the sky is 76. If the horizontal distance between the building and the hot air balloon is 354 feet, find the height of the hot air balloon

The figure is shown below:

Let the height of the balloon is AD, the height of the building is BC.

Draw a line BE parallel to CD.

Therefore, AD=x+95, BC=95 and BE=CD=354 ft

Now in triangle [tex]ABE[/tex].

[tex]\tan\theta=\dfrac{\text{Opp}}{\text{Adj}}[/tex]

[tex]\tan76^{\circ}=\dfrac{AE}{BE}[/tex]

[tex]AE\approx 4.01\times 354[/tex]

[tex]AE\approx 1419.54[/tex]

The height air balloon is 1419.54+95 =1514.54 ft

Hence, the height of the hot air balloon is 1514.54 feet approximately.

Answer: It took 13 hours by her to ride 164.45 miles.

Step-by-step explanation:

Total distance =  164.45 miles

Average distance traveled = 12.65 miles per hour  (speed)

[tex]Time = \dfrac{Distance}{Speed}[/tex]

[tex]Time = \dfrac{164.45}{12.65}=\dfrac{16445}{1265}\\\\=13\text{ hours}[/tex]

Hence, it took 13 hours by her to ride 164.45 miles.
