Answer:
Midpoint = (-3, 4.25)
Step-by-step explanation:
<span>5-4(-3x)=-36
5+12x = -36
12x = -36 - 5
12x = -41
x = -41/12
</span>5-4(3x)=-36
5 - 12x = -36
-12x = -41
x = 41/12
answer: solutions x = - 41/12 and x = 41/12
We can use the vertical angle theorem which states that any two opposite angles are congruent. So, you can just set the two measures equal to each other and solve for x:
So, your answer is
20°.
