Answer:
120º
Step-by-step explanation:
angles of an equilateral triangle are equal so..
180 ÷ 3 = 60º
to get the exterior m⦣C
180 - interior m⦣C = exterior m⦣C
180º - 60º = 120º
Group up the like terms and combine them
2x^2 and -7x^2 add up to -5x^2
6x and 2x add up to 8x
1 and -3 add up to -2
We end up with -5x^2 + 8x - 2
