y = ___ °
enter the answer
check it

Explanation:

Step1: Assume the total angle is 90 degrees.

Let's assume the whole angle is a right - angle, so the sum of all the small angles is 90 degrees. And there are 5 equal angles labeled as y.

Step2: Set up an equation.

The equation is 5y = 90.

Step3: Solve for y.

Divide both sides of the equation by 5: $y=\frac{90}{5}=18$.

Answer:

18
