Answer:
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
<em>In the right triangle ABC</em>
-----> by a 45°-90°-45° triangle
so
substitute the values
<em>In the right triangle BCD</em>
substitute the values
6 ft
Step-by-step explanation:
We’ll use the trigonometric rule of SOHCAHTOA;
Well use <em>TOA</em> – since we know the value of the adjacent side and we are evaluating for the opposite side;
Tan Φ = Opposite / Adjacent
Tan 36 = x / 8
x = Tan 36 * 8
x = 5.81234
x = 6 ft
