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!
