Question

one angle is twice another angle. The sum of the angle is 90 degrees. How many degrees are in each angle?

Answer 1

45 degrees is the answer

Answer 2

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!
