Answer:
x = y = 4
Step-by-step explanation:
Using the cosine ratio in the right triangle and the exact value
cos45° = , then
cos45° = =
( multiply both sides by 8 )
8 × cos45° = x , then
x = 8 × = 4
The third angle in the triangle = 45° ( sum of angles in triangle )
Then the triangle is isosceles with congruent legs, thus
x = y = 4
