Answer:
5
Step-by-step explanation:
5x=12+3
5x=15
X=15/3
X=5
Answer:
proportional: 1, 3,5,6,8,10
non: 2,4,7,9,11,12
15)
an exterior angle equals the sum of the remote interior angles
<span>so
m<XYT = m<X + m<Z
4x - 25 = x + 15 + 50 - 3x
4x - 25 = -2x + 65
6x = 90
x = 15
answer
x = 15

First option is the correct answer
Answer:
∠x = 92°
Step-by-step explanation:
Supplementary means that the angles add up to 180°. Since one of them equals 88°, the other one or ∠x equals:
So, ∠x = 92°
