Answer:

Answer D is correct

Step-by-step explanation:

Given that,

<R = 3x + 4

<T = 4x - 10

<S =?

We know that the sum of the interior angles in a triangle is added up to 180°.

So,

<R + <T + <S = 180

3x + 4 + 4x - 10 + <S = 180

7x - 6 + <S = 180

<S = 180 + 6 - 7x

<S = 186 - 7x

<S = ( 186 - 7x )°
