Answer:
x = 70; the labeled angles are 110º and 70º.
Step-by-step explanation:
The full degrees will add up to 180º. There are 2x and +40.
Equation: 
Solve: 
Since x=70, 70+40 will equal to 110.
Therefore, "x = 70; the labeled angles are 110º and 70º." is correct.
It depends if the one side is in between the angles or not.
Answer:
1) 6x-10y=7 2)5x-3y=8
Step-by-step explanation:
Answer:
A. 4(2y-9)
Step-by-step explanation:
Both terms are divisable by 4 and would bring them to the smallest whole degree
Remember Pedmas. 1) -12+3(3)+5 = -12+9+5 = 2. 2) 3(15-12)-5 = 3(3)-5 = 4
