Answer:
x = 8
∠B = 70°
Step-by-step explanation:
∠A = ∠B through alternate exterior angles.
∠A = ∠B
8x + 6 = 4x + 38
8x - 4x + 6 = 38
4x + 6 = 38
4x = 38 - 6
4x = 32
x = 32 ÷ 4
∠B = 4x + 38
4(8) + 38
32 + 38
= 70
Answer: 70
8x+6=4x+38
4x=32
x=8
<B=4x+38=4*8+38=70
0,0
X = -7
If T is the midpoint, then that means its exactly 1/2 of the way between 2 points
this means we can set the 2 given values equal
4x - 3 = 2x + 7
first move like terms to the same side
2x = 10
x = 5
now that we know the length of x, we plug it back in to get the length
4x - 3 + 2x + 7 = 6x + 4
6(5) + 4 = 34
