PLEASE HELP ASAP!!! I NEED CORRECT ANSWERS ONLY PLEASE!!!

Answer 1

Answer:

The answer to your question is 4.5

Step-by-step explanation:

Data

hypotenuse = h = 6

angle = α = 42°

adjacent side = DE

Process

Use trigonometric functions to solve this problem

1.- The trigonometric function that relates the adjacent side and the hypotenuse is cosine

Cosα = $\frac{adjacent side}{hypotenuse}$

Solve for adjacent side = DE

        DE = hypotenuse x cos α

Substitution

        DE = 6 x cos 42

Simplification

         DE = 6(0.74)

Result

         DE = 4.5
