Answer:
I would say 45
Step-by-step explanation:
180-90=90
90/2=45
-9 - 7(-4v + 1)
-9 - 7(-4v) - 7(1)
-9 + 28v - 7
28v - 9 - 7
28v - 16
Answer:
2x+6
Step-by-step explanation:
use distributive property
a(b+c)
=
ab+ac

This will involve finding an arctangent.
We'll consider the woman's height as the "opposite" side of a triangle and the shadow as the "adjacent" side. The angle that the Sun makes equals the arc tangent of that angle.
tan (Sun's angle) = 71" / 36"
tan (Sun's angle) =

<span>
1.9722222222
</span>

when we determine the arc tangent of 1.9722222222, it will equal the Sun's angle.
arc tangent of 1.9722222222 = 63.113 degrees
