Question

Given that ∠A and ∠B are vertical angles, m∠A = 7x+5 and m∠B = 8x-23, what is the value of x

Answer 1

Answer: x=28

Step-by-step explanation: this equates to 7x+5=8x-23. To find the value of x, solve for it.

add 23 to both sides to get 7x+28=8x. subtracting 7x from both sides gives us x = 28
