Answer:
25.75° degrees
Step-by-step explanation:
Complementary angles are two angles that add to 90 degrees. This means that the complementary angle to 64.25 would be:
90 - 64.25
= 25.75°
see below
2/3y + 15 = 9
Subtract 15 from each side
2/3y + 15-15 = 9-15
2/3y = -6
Multiply each side by 3/2 to isolate y
3/2 * 2/3y = -6 *3/2
y = -9
5/4
6/1
