Answer:
x=10°
5x=50°
2x=20°
Step-by-step explanation:
The sum of angles in a triangle is 180°, so 5x°+2x°+110° must be equal to 180. So solving this equation we get 5x+2x+110=180, 7x+110=180, 7x=70, and x=10, so our answer is x=10.
Now to find 5x, we multiply by 5, and get 5x=50
To find 2x, we multiply x by 2, and get 2x=20.
