Question

The measures of two complementary angles are (2x-7)°and (X+4)°.Find X.

Answer 1

Answer:

61

Step-by-step explanation:

sum of complementary angle is 180

$2x - 7 + x + 4 = 180 \\ 3x = 180 + 3 \\ 3x = 183 \\ x = 183 \div 3 \\ x = 61 ^{0}$

Answer 2

Step-by-step explanation:

2x-7+x+4=90 .... since they are complementary their sum will be 90°

3x-3=90

3x=90-3

3x=87

x=29
