Answer:
Step-by-step explanation:
Hello There!
If you didn't know vertical angles are congruent
That being said we can use this equation to solve for x
40 = 5x
Objective: Isolate the variable using inverse operations
To get rid of the 5 we divide each side by 5
40 / 5= 8
5x/5=x
we're left with x=8
To check our answer we can plug in 8 to x and if it equal 40 then the answer is correct
5(8) = 40
So the answer would be 8
