Question

Two complementary angles are x + 15 and 2x – 54. Find x and the measure of each angle.

Answer 1

Answer:

x=43

x+15=58

2x-54=32

Step-by-step explanation:

complementary angles means the sum is equal to 90°

therefore,

x+15+2x-54=90°

3x-39=90°

3x=90+39

x=129/3

x=43

Hope it helps

Answer 2

Answer:

x = 43

Step-by-step explanation:

x + 15 + 2x - 54= 90

3x - 39=90

3x. = 90 + 39

=129

x. =129÷3

x =43
