Answer:
m∠B=143°
Step-by-step explanation:
we know that
<u><em>Vertical Angles</em></u> are the angles opposite each other when two lines cross. They are always equal
so
In this problem we have that
m∠A=m∠B ----> by vertical angles
substitute the given values and solve for x
Find the measure of angle B
m∠B=(5x-7)°
substitute the value of x
m∠B=(5(30)-7)°
m∠B=143°
Answer:
I believe the anwser would have to be -3
Step-by-step explanation:
4s=10s-18
-6s=18
then divide by -6
-6/18=-3
then plug -3 into the s value
X=66 im pretty sure......
