Answer:
52.5
Step-by-step explanation:
Since this is an isosceles triangle, the base angles are the same
The three angles add to 180
R+ T + S = 180
3x+30 + 3x+30 + 12x-15 = 180
Combine like terms
18x +45 = 180
Subtract 45 from each side
18x+45 - 45 = 180-45
18x =135
Divide each side by 18
18x/18 = 135/18
x = 7.5
We want angle R
R = 3x+30
= 3( 7.5) +30
22.5 +30
52.5
