Triangle ABC is a right triangle.
Triangle A B C. Angle A is x degrees, B is 90 degrees, C is (x minus 10) degrees. The exterior angle to angle C is (2 x + 40) degrees.
Which equations can be used to find the value of x? Check all that apply.
1. x + 90 + (x minus 10) = 180
2. x + 90 + (2 x + 40) = 180
3. 2 x + 80 = 180
4. x + 90 = 2 x + 40
5. (x minus 10) + 90 = 2 x + 40
