the sum of complementary angles is 90°
so
x+4+2x-7=90°
3x+4-7=90°
3x-3=90°
3x=90+3°
3x=93°
x=93÷3
x=31°
so
x+4+2x-7=90°
3x+4-7=90°
3x-3=90°
3x=90+3°
3x=93°
x=93÷3
x=31°

Hi !
We know that ,
Complementary angles are those whose angle sum is 90°.
Hence,
According to the question,
(x + 4)° + (2x - 7)° = 90°
(3x - 3)° = 90°
3x = 93
x = 93/3
x = 31°
