One angle is twice another angle. the sum of the angle is 90 degrees. how many degrees are in each angle?

Hello!

You can make equations based on what you know

Let x stand for angle 1
Let y stand for angle 2

x + y = 90
x = 2y

You can put x into the other equation

2y + y = 90

Combine like terms

3y = 90

Divide both sides by 3

y = 30

Know you can put y into the other equation

x + 30 = 90

Subtract 30 from both sides

x = 60

The answers are 30 and 60

Hope this helps!
