Answer:
a=9
c= 17.5
angles: a =31, b =59, c =90
Step-by-step explanation:
a:
tan (31) = a/15 *cross multiply*
a = 15 (tan (31))
a = 9
c:
*use pythagorean theorum*
9^2 + 15^2 = c^2
81 + 225 = c^2
306 = c^2
17.5 = c
Answer:
B = 59
a = 9.01
c = 17.49
Step-by-step explanation:
Angle B
180 - 90 - 31 = 59
c
The sine of an angle is equal to the ratio of the opposite side to the hypotenuse.
sin(B)=opp/hyp
sin(B)=15/c
sin(59)=15/c
c=15/sin(59)
c=17.49
Find the last side of the triangle using the Pythagorean theorem.
[tex]a^{2} +b^{2} =c^{2} \\a^{2} +15^{2} =17.49^{2} \\\\a^{2} =17.49^{2} -15^{2}\\a=9.01[/tex]

Answers
Answer:
20
Step-by-step explanation:
We are to determine the lowest common multiple of 4 and 5
the first six multiple of 4 are = 4, 8, 12, 16, 20, 24
the first six multiple of 5 are = 5, 10, 15, 20, 25
the multiple they both have in common is 20
Solve 6 - 2x = 3
How do I do this?
Answers
Answer:
x = 3/2 or 1.5
Step-by-step explanation:
6 - 2x = 3
(You have to subtract 6 on both sides so it can cancel out)
6 - 6 - 2x = 3 - 6
-2x = -3
(Now, you divide -2 on both sides to isolate the x)
-2/(-2)x = -3/(-2)
x = 3/2

Keisha's softball team won 60% of 135 games, how much games did the team lose?
Answers
Answer:
54
Step-by-step explanation:
135(.6) = 81
total = 135
won = 81
lost = 54
OR you could just multiply 135 by 110%-60%, which is 40% or 0.4
135(.4) = 54

Graph the circle which is centered at (-3, -2), and
which has the point (-3, -9) on it.
Answers
Answer:
(x+3)² + (y+2)² = 49
Step-by-step explanation:
To graph the circle that has centre of (-3,-2) with a point (-3, -9) on it.
First, let us write the equation of the circle
The equation is expressed as;
(x-a)² + (y-b)² = r²
(a, b) is the centre
r is the radius
r = √(-9-(-2))² +(-3-(-3))²
r = √(-9+2)² +(-3-(-3))²
r = √(-7)²
r = √47
r = 7
Get the equaton
(x-(-3))² + (y-(-2))² = 7²
(x+3)² + (y+2)² = 49
This gives the required equation

Answers
Answer:
x = 10
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Add 4 to both sides of the equation:
x - 4 (+4) = 6 (+4)
x = 6 + 4
x = 10
x = 10 is your answer.
~
You get this result after adding 4 to both sides. This is to undo the "minus 4" happening to the x.
To check the answer, replace x with 10 and simplify each side like so
x-4 = 6
10-4 = 6
6 = 6
We get the same thing on both sides, so that confirms the solution.

for positive acute angles A and B, it is known that cos A=9/41 and tan B=21/20. Find the value of sin(A+B) in simplest form.
Answers
Answer:
Step-by-step explanation:
I attached a pic so you can see what the angles look like when you draw them out and construct right triangles out of them. We need to find the missing side lengths, ?, in each triangle. For A:
and
x = 40 For B:
and
x = 29. Now that we know all the sides of each triangle, we will use the sum identity for sin:
sin(A + B) = sinAcosB + cosAsinB. Filling in what we found in our triangles for each ratio: sin A = 40/41, sin B = 21/29, and cos B = 20/29
sin(A + B) = which simplifies to

It snows 0.7 inch on Wednesday and 0.31 inch on Thursday. Brandon draws this model to find how much more snow fell on Wednesday than on Thursday.
Answers
Answer: 0.39 inch snow fell on Wednesday than on Thursday.
Step-by-step explanation:
We are given that, It snows 0.7 inch on Wednesday and 0.31 inch on Thursday.
According to this model,
more snow fell on Wdifferenceednesday than on Thursday because 0.7 > 0.31
To compute the difference we subtract the length of snow on Thursday from length of snow on Wednesday.
Difference = 0.7-0.31
= 0.39 inch
Hence, 0.39 inch snow fell on Wednesday than on Thursday.
