Answer:
x=31
Step-by-step explanation:
as they are complementary
then 2x-7+x+4=90
= 3x-3=90
= 3x=93
so x=31

Answer:
The sum of two complementary angles equals to 90°
(2x - 7) + (x + 4) = 90°
2x - 7 + x + 4 = 90°
2x + x - 7 + 4 = 90°
3x - 3 = 90°
3x = 90° + 3
3x = 93°
x = 93° ÷ 3
x = 31°
1st angle = (2x - 7)
= 2 × 31° - 7
= 62° - 7
= 55°
2nd angle = (x + 4)
= 31° + 4
= 35°
Hope it helps
