Respuesta :

T + S + R = 180

R = 180 - (T + S)

T + S = 68 + 76  = 144

So R = 180 - 144  = 36

<R = 36

Because the total degrees a triangle has is 180 degrees, just add the two degrees we have and subtract that from 180 degrees to get the answer.

68 + 76 = 144
180 - 144 = 36

So, angle R is equal to 36 degrees.
