Answer:
x = 10
5x = 50
2x = 20
Step-by-step explanation:
This is a triangle, so all the angles will equal 180, so you can set up the equation like so:
110 + 5x + 2x = 180
COmbine like terms:
110 + 7x = 180
Subtract 110 from each side:
7x = 70
divide each side by 7:
x=10
Substitute to find the values of the angles:
5x
5 ( 10 )
50
2x
2 ( 10 )
20
