Answer:
see below
Step-by-step explanation:
The sum of the angles of a triangle is 180
x+15 + 2x+8 + 11x+3 = 180
Combine like terms
14x + 26 = 180
Subtract 26 from each side
14x+26-26 =180-26
14x = 154
Divide by 14
14x/14 = 154/14
x=11
<S = x+15 = 11+15 =26
<T = 2x+8 = 2*11+8 = 22+8 = 30
<T = 11x+3 = 11*11 +3 = 121+3 = 124
