Step-by-step explanation:
I think this is angles topic.
related with right angles and adjacent angles.
Let the number be x
X *8 = 8x
8x-66= twice of the number
8x-66=2x
-66=2x-8x
-66=-6x
Divide both sides by -6
X=11
Answer:
Since they are vertical angles (or angles opposite each other), you set them equal to each other.
5x + 4 = 74
5x = 70
x = 15
