this made me realize how dumb I am
First solve the equation:
5(3x-7)=20 => 15x - 35 = 20 => 15x = 55 => x=11/3
Fill in this solution in 6x-8:
6*11/3 - 8 = 22 - 8 = 14
Second question: apply the distributive property (ie,. both terms get multiplied by 4/5):
4/5(20x - 10) = 80/5x - 40/5 = 16x - 8

Answer:
You simply take the values away from 180°.
a) 180-85-65 = 30°
b) 180-37-63=80°
c) 180-52-78=50°
d) 180-102-58=20°
e) 180-100-60=20°
f) 180-105-25=50°
g) 180-127-23=30°
