Complementary angles

Answer 1

1) correct

2) correct

3) incorrect, x = 11

4) incorrect, x = 50

Explanation:

3) 90-35 = 5x

5x = 55

x = 11

4) 90-56 = (x-16)

x-16 = 34

x = 50

Answer 2

Explanation:

3) 5x + 35 = 90 {Complementary angles}

5x = 90 - 35

5x = 55

x = 55/5

x = 11

4) 56 +x - 16 = 90 {Complementary angles}

x + 40 = 90

x = 90 - 40

x = 50
