Answer:
D
Step-by-step explanation:
Since x is the measure of the third angle and all 3 angles are congruent then
All 3 angles have a measure of x
The sum of the 3 angles in a triangle = 180°, this
x + x + x = 180 ← is the required equation
3x = 180 ( divide both sides by 3 )
x = 60

Answer:
-11x +3y + 25
Step-by-step explanation:
7-8x+4y+18-3x-y
= -8x-3x +4y-y +18+7 (putting like terms together)
= -11x +3y + 25 (Adding like terms)
