Can someone help me with this trigonometry question
==================================================
Explanation:
Apply the law of cosines to find angle C
c^2 = a^2 + b^2 - 2*a*b*cos(C)
19^2 = 11^2 + 17^2 - 2*11*17*cos(C)
361 = 121 + 289 - 374*cos(C)
361 = 410 - 374*cos(C)
361 - 410 = -374*cos(C)
-49 = -374*cos(C)
-374*cos(C) = -49
cos(C) = (-49)/(-374)
cos(C) = 0.131016042780749 ..... which is approximate
C = arccos(0.131016042780749)
C = 82.4716905247836
C = 82 degrees
Notes:
arccos is shorthand for "arccosine". It is the same as inverse sine.Make sure your calculator is in degree mode. You can check by computing cos(60) and you should get 0.5Which is the best estimate of the difference between 6 7/8 and 2 1/8?

Step-by-step explanation:
For the problem:
3 1
2
÷

= ?
Convert any mixed numbers to fractions:
3 1

Once rearranged, multiply all of the numerators by each other. Do the same with the denominators and form a new fraction with these values:
7 × 2
2 × 1
=

You earned $44.55 in 9 hours.Your friend earns $51 in 12 hours.How much do you and your friend each together earn if you work 20 hours?
Answer:
4.95 * 20 = 99 your earnings
4.25 * 20 = 85 friends earnings
Step-by-step explanation:
44.55/9 = hourly earnings
4.95 per hour
51/12= hourly earnings
4.25 per hour
4.95 * 20 = 99 your earnings
4.25 * 20 = 85 friends earnings
finding side length of the 90-degree angle triangle
Answer:
x = 4
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin45° = [tex]\frac{1}{\sqrt{2} }[/tex]
sin45° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{4\sqrt{2} }[/tex] = [tex]\frac{1}{\sqrt{2} }[/tex] ( cross- multiply )
[tex]\sqrt{2}[/tex] x = 4[tex]\sqrt{2}[/tex] ( divide both sides by [tex]\sqrt{2}[/tex] )
x = 4

Step-by-step explanation:
Jorge Claims that the distance between his house and the library is 13 miles. His city is placed on a coordinate plane. Jorge's House is at the coordinates (5, 1), the mall is at coordinates (2, 11) and hte Library is at cordinates (10, 13). What equation verifies his claim?
Answer:
House coordinate = (5, 1)
Library coordinate = (10, 13)
Step-by-step explanation:
Given :
House coordinate = (5, 1)
Library coordinate = (10, 13)
Distance between house snd library :
Distance = sqrt[(x2 - x1)² + (y2 - y1)]
x1 = 5, x2 = 10, y1 = 1, y2 = 13
Distance = sqrt[(10 - 5)² + (13 - 1)²]
Distance = sqrt[(5² + 12²)]
Distance = sqrt(25 +144)
Distance = sqrt(169)
Distance = 13
Help me pls i dont understand this
Step-by-step explanation:
Notice that:
15x = 5 * 3x and 10y = 5 * 2y.
Since there is a common factor of 5,
we can take out the factor.
=> 15x + 10y = (5)(3x) + (5)(2y) = 5(3x + 2y).
for what value of the variable is the value of the expression -3(2x+1) is 20 greater than the expression 8x+5
Answer:
- 3 ( 2x+1 ) 20
8x+5
_____________
8x+5×20 -3 ( 2×12.5+1 )
8×=100 -3 ( 25+1 )
100÷8= 12.5 -3 ( 26 )
×= 12.5
-3 ( 26 )
-3×2 + -3×6 = -6+ -18 = -24
-24

Determine the value of x, y, w and z.. Round to the nearest tenths place if necessary.
X =
y =
W =
Z=
Answer:
w=5 x=2.1 y=5.4 z= 14.1
Step-by-step explanation:
w² = 13² - 12² = 25
w = 5
cos ∠1 = 12/13 = 13/(12+x)
12 (12+x) = 13 x 13 = 169
144 + 12x = 169
12x = 25
x = 25/12 = 2.08 = 2.1
∠1 + ∠2 = 90°
∠2 + ∠4= 90° ∠4 = ∠1
sin ∠4 = x/y = sin ∠1 = 5/13
5y = 13x
y = 13/5 x = 13/5 * 25/12 = 65/12 = 5.4
z = 12 + x = 12 + 2.08 = 14.08 = 14.1

An invertible function is represented by the values in the table.
Which graph shows the inverse of this function?
Answer:
Graph B
Step-by-step explanation:
Because th inverse fuction is f^-1(x), you basicaly swap the numbers, all x valuese would equal y.
In this exercise we have to identify the treated inverse function and the graph that corresponds to it, so we have that what corresponds to this is:
Graph B corresponds to the given function.
In this way, the inverse function corresponding to:
[tex]f^{-1}(x)[/tex]
Because th inverse fuction is f^-1(x), you basicaly swap the numbers, all x valuese would equal y. So we will have that the graph that correctly corresponds to this function is graph B.

A wooden box has a square base. The height of this box is 3 times the length of one side of the base. If one side of the base is 3 feet long, what is the volume of this box?
Answer:
[tex]V=81\ \text{feet}^3[/tex]
Step-by-step explanation:
A wooden box has a square base
One side of the base is 3 feet
The height of this box is 3 times the length of one side of the base, h = 3(3) = 9 feet.
The volume of the box is given by :
[tex]V=A\times h[/tex]
A is area of base
For square base, A = side²
[tex]V=3^2\times 9\\\\=81\ \text{feet}^3[/tex]
So, the volume of this box is [tex]81\ \text{feet}^3[/tex]

HEEEEEELP IF U CAN EXPLAIN PLEASO DO IT TANK U
Answer:
130 degrees
Step-by-step explanation
Angle 6 is 130 degrees because it has a vertical angle relationship with the angle measure of 130 degree
Angle 6 and 2 are equal because of the corresponding angle relationship
OR
The angle measure of 130 degrees have an alternate interior angle relationship with angle 2 which makes them equal
Therefore angle 2 is 130
