Answer:
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
