What is the measure of NRS?
never [62]

Answer:

<h3>C. 113°</h3>

Step-by-step explanation:

(7x - 1) + 79° = 21x + 8

• An exterior angle of a triangle is equal to the sum of its two interior opposite angles.

(7x - 1) +79  = 21x + 8 \\ 7x - 1 + 79 = 21x + 8 \\ 7x +  78 = 21x + 8 \\ 78 - 8 = 21x - 7x \\ 70 = 14x \\  \frac{70}{14}  = x \\ 5 = x \\

NRS = 21x + 8

21x + 8 \\ 21(5) + 8 \\ 105 + 8 \\  {113}^{o}
