<span>m//n if the external alternating angles are equal, that means:
(3x+12)°=48°
Solving for x:
3x+12=48
3x+12-12=48-12
3x=36
3x/3=36/3
x=12
Answer: Option B. 12</span>
The answer should be 0.06
Step-by-step explanation:
2x + 7x - 10 = 180° because these rwo angles are supplementary
10x - 10 = 180°
10x = 190° divide both sides by 10
x = 19
measure of angle on the right:
8x - 10 ➡ 8 × 19 - 10 = 142°
measure of angle on the left:
2x ➡ 2 × 19 = 38°
Answer: A is the right anwser.
