Find the value of x in each figure. (1-4) Download pdf

3,20,55,30

1.) x = 3

2.) x = 20

3.) x = 55

4.) x = 30

Step-by-step explanation:

when ever I do these types of equations I always base it off a number that either makes the measurement a right angle or a 180 angle which makes measuring it easier.

1.) 180 - 165 = 15/5 = 3 meaning x=3

2.) 90 - 76 = 14+6 = 20 meaning x = 20

3.) 90-20 = 70 - 15 = 55 meaning x=55

4.) 180 - 90=90/3 = 30 meaning x = 30
