What is the measure of angle R?
amid [387]

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
