Tell whether the angles are complementary or supplementary. Then find the value of x.

the angles are complementary because they add up to 90° because of the red square. x=20

Step-by-step explanation:

4x-5+15=90

4x+10=90 subtract 10 from each side

then you get left with 4x=80

divide 4 from each side then you get left with x=20 and to check just substitute  20 where x is so 4(20)-5= 80-5=75 +15=90.
