For the triangle shown, find section x.

if you can explain the answer that would be great, you

D

Step-by-step explanation:

Using the trigonometric identity

• tan²x + 1 = sec²x

tanx = = , thus

sec²x = ()² + 1

         = + =

Take the square root of both sides

secx = = → D

step-by-step explanation:

first, eliminate the parenthesis:
