What is the answer need ASAP

Answer 1

C. 58°

Step-by-step explanation

The sum of the interior angles of a triangle is 180°.

We sum all the three angles to obtain,

`8x+(14x+2)+(10x+50)=180`.

We group like terms to get,

`8x+14x+10x+2+50=180`.

Simplify,

`32x+52=180`.

Combine like terms to get,

`32x=180-52`.

Simplify,

`32x=128`.

Divide both sides by 32 to get,

`x=4`.

We substitute the value of x into the expression for

`m\:<\:R=14x+2`.

This implies that,

`m\:<\:R=14(4)+2`.

`m\:<\:R=56+2`.

`m\:<\:R=58`.

The correct answer is C
