Answer:
1. Distributive
Step-by-step explanation:
This is because you multiply the number outside the parentheses into the numbers inside the parentheses.
Hope it helped.
Your first equation would be:
65 + 3x - 10 + 2x = 180
Then simplify to get:
5x + 55 = 180
Subtract 55 from each side:
5x = 125
Now divide by 5 to find x:
x = 25
The measure of angle B = 65
The measure of angle C = 50
Hope this helps!! :)
