The measure of two vertical angles are given by the expressions (x+3) and (2x-7). Find the value of x.

Answer:
61.3
Step-by-step explanation:
two vertical angles add up to 180°
so (x+3)+(2x+7)=180°
open brackets & collect like terms
x+3+2x-7=180°
3x+-4=180°
3x=184°
x=61.3 after dividing by 3 on both sides
