Answer:
6
Step-by-step explanation:
6s^2=s^3
divide by s^2 on both sides to get 6=s. There is your answer
Y - y1 = m(x - x1)
slope(m) = -5
(4,1)...x1 = 4 and y1 = 1
now we sub
y - 1 = -5(x - 4) <===
Manipulating the left side of the equation, we obtain:

Using that

:
Hey there! :D
Vertical angles are congruent, they have the same measure.
So, <7 and <5 are vertical angles. They share the same vertex, and if you were to draw a straight line between them, it would connect and bisect them both equally.
<5= 45, so <7= 45.
I hope this helps!
