Find x and y (45-45-90 formula)

(It’s not 5.6 for x and y I got that wrong)

I’ll mark as brainliest!!

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

answer: just subtact the units and then add the non negative : happy to
