Answer:
x=9 and angle B=40
Step-by-step explanation:
5x-5=3x+13
Subtract -3 on both sides of x
5x(-3)-5=3x(-3)=+13
2x-5=13
Add 5 to both sides
2x-5(+5)=13(+5)
2x=18
Divide by 2
x=9
Now that you know x=9, plug it into 3x+13
So, 3(9)+13= 27+13= 40
so ya thats my answer hopefully it helps
(btw both angle A and B are the same so thats why u put them equal)
