Find the value of x express your answer in simplest form

Use Pythagorean Theorem which is a squared (one of the numbers thats side is with the 90° angle) plus b squared (the other number thats side is next to the 90° angle) equals c squared (the hypotenuse).

Step-by-step explanation:

5.7 or 6 (simplest form)

Step-by-step explanation:

Angle = 45°

Adjacent = x

Hypotenuse = 8

Cos(angle) = Adj/Hyp

Cos 45° = x/8

cross multiply

x = 8 x Cos 45

x = 8 x 0.7071

x = 5.67 or 5.7 or 6
