What’s the answer for this question

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.

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
