Answer:

see explanation

Step-by-step explanation:

13

The 2 angles form a straight line and sum to 180° , that is

x + 30 = 180 ( subtract 30 from both sides )

x = 150

14

Similarly

x + 125 = 180 ( subtract125 from both sides )

x = 55

15

The 2 angles form a right angle, then

x + 27 = 90 ( subtract 27 from both sides )

x = 63

16

The 2 angles form a complete revolution of 360° , then

x + 35 = 360 ( subtract 35 from both sides )

x = 325
