Answer:
Solve by using the steps of the Pythagorean Theorem. The answer is down below.
Step-by-step explanation:
1) a^2 + b^2 = c^2
2) 15^2 + 20^2 = c^2
3) 225 + 400 = c^2
4) 625 = c^2
5) √625 = √c^2
6) 25=c
Answer:
the measure of C is 90°
Step-by-step explanation:
it's a right angle
all right angles are 90°
Right now the equations are in standard form, which is ax+by=c. You need to put them in the form y=x and then divide the equations by 3 since y itself is being multiplied by 3. And then graph them as you normally would
Hope this helps!
Answer:
60.28.
Step-by-step explanation:
We need the sine function because we are given the opposite side and we need the hypotenuse.
sin 71 = 57 / x
Cross multiply
x * sin 71 = 57
x = 57 / sin 71
= 60.28.
