Answer 1

1. Let the angle = x
the complementary = y

x + y = 90
x - y  = 34 -
-----------------
2y = 56
y = 56 : 2
y = 28°

x + y = 90
x + 28 = 90
x = 90 - 28
x = 62°

The pair of complementary angles is 62° and 28°

2. Let the angle = x

x = 4(90 - x) - 25
x = 360 - 4x - 25
x + 4x = 335
5x = 335
x = 335 : 5
x = 67°

3. Let the angle = x

a. x = (180 - x) + 48
x = 180 - x + 48
x + x = 228
2x = 228
x = 228 : 2
x = 114°

b. x = 1/9 × (90 - x) (multiply with 9 for both sides)
9x = 90 - x
9x + x = 90
10x = 90
x = 90 : 10
x = 9°
