Answer:
The answer to your question is x = 11√2 or 15.56
Step-by-step explanation:
Data
Right triangle
hypotenuse = 22
angle = 45°
adjacent side = 45°
To solve this problem, use trigonometric functions. The trigonometric function that relates the adjacent side and the hypotenuse is cosine.
cos Ф = Adjacent side / hypotenuse
-Solve for adjacent side
Adjacent side = hypotenuse x cos Ф
-Find cos 45° = √2 / 2
-Substitution
Adjacent side = (22)(√2 /2)
Adjacent side = 11√2 or 15.56
