3d - e = 7d + e = 5 ⇒ 3d - e = 5
7d + e = 5

3d - e = 5
7d + e = 5 +
-----------------------
10d / = 10
10d = 10
d = 10/10
d = 1

7d + e = 5
7×1 + e = 5
7 + e = 5
e = 5 - 7
e = -2

a vertical pole 10 ft. tall casts a 14-foot shadow. what is the angle of elevation of the sun to the nearest degree?

PtichkaEL [24]

Draw a right triangle.

$tan(theta) = \frac{opposite}{adjacent}$

$tan(theta) = \frac{10}{14}$

Arctangent (tan^-1) can be used to find theta.

$tan^{-1}(\frac{10}{14})=theta$

$theta\ is\ approx\ \boxed{36\ degrees}$
