Answer:
PLace them one by one from big number to small and the middle number is the answer.
Step-by-step explanation:
All 3 angles of a triangle must equal to 180. You can simply set up an equation to solve this and set it equal to 180.
Angle 1 - 50 + x
Angle 2 - x
Angle 3 - 2x -10
50+x+x+2x-10=180
4x+40=180
4x=140
x=35
Angle 1 = 50+35= 85
Angle 2 = 35
Angle 3 = 2(35) - 10 = 60
60+35+85=180
The expression, if that's what ur looking for, is 1(x)+4 or just x+4
All real numbers or is it multiple choice
