Answer:
x=35
Step-by-step explanation:
So the line XYZ is 180. The angles together should equal 180 in total.
The equation would be (2x-5) + (3x+10) = 180.
2x-5+3x+10=180
You want to combine like terms.
2x+3x and -5+10
5x+5=180
subtract 5 from both sides. Need variable alone.
5x+5(-5)=180(-5)
5-5 is 0 and 180-5 is 175
5x=175
Divide by 5 on both sides.
5x/5=175/5
x=35
