Question

find the value of X in the given figures

Answer 1

Answer:

1.) x = 105°

2.) x = 60°

3.) x = 125°

Answer 2

Step-by-step explanation:

angle sum property of traingle

x + 45 + 30 = 180

x + 75 =180

x = 180 -75

x = 105

x + 90 + 30 =180

x + 120 =180

x = 180- 120

x = 60

exterior angle property

65 + 60 = x

x = 125
