Answer:
x = 16
m<R = 34°
Step-by-step explanation:
▪︎Its an isoceles triangle, so the two opposite angles are equal. m<S = <T.
▪︎So, you write them equal to each other and solve the linear equation to find x.
▪︎Substitute the x value into any of the angles and multiply by 2, (as they are equal) to find the sum, which is 146°.
▪︎Sum of all angles in a triangle is 180°,so
146° + m< R =180°
▪︎than minus 146° from 180°.
▪︎And you will have your answer.
