Two angles are complementary is the sum of their measures is 90 degrees. The measure of the first angle is 36 degrees more than
3 times the second angle. Find the measure of the first angle
1 answer:
x+ y = 90
x = 36 + 3y
x = 36 + 3(90 - x)
x = 36 + 270 - 3x
4x = 306
x = 153/2 = 76.5 degrees
Answer: 76.5 degrees
Check: y=90=76.5 = 13.5 degrees
3y+36 =3(13.5)+36 = 76.5 good
