Answer:
<V = 28
<C = 116
<R = 36
Step-by-step explanation:
We know that the sum of the angles of a triangle is 180 degrees.
2x+4 + 10x-4 + 3x = 180
Combine like terms.
2x+3x+10x +4-4 = 180
15x = 180
Divide each side by 15.
15x/15 = 180/15
x = 12
Now we can find each angle.
<V = 2x+4 = 2*12+4 = 24+4 = 28
<C = 10x-4 = 10*12-4 = 120-4 = 116
<R = 3*x = 3*12 = 36
