Answer:

22.5

Explanation:

90/4=22.5

now I know what you're thinking how could this possibly be the right answer but let me explain on the opposite side of you x is a 90-degree angle so to make the other side equal 90 we just add the 3x and x to get 4x the divide both sides by 4 and you'll end up with x=22.5

Answer:

x = 22.5°

Explanation:

A right angle is represented by the symbol ∟ and measures 90°

Sum of angles on a straight line = 180°

Therefore, 90 + x + 3x = 180

combine like terms:

⇒ 90 + 4x = 180

subtract 90 from both sides:

⇒ 4x = 90

Divide both sides by 4

⇒ x = 22.5
