Answer:

A. 36°

Step-by-step explanation:

Given:

m<NST = 15x - 4

m<RSN = 6x

m<RST = 122°

Required:

m<RSN

Solution:

First we need to create an equation to determine the value of x.

Thus:

m<NST + m<RSN = 122° => angle addition postulate

15x - 4 + 6x = 122 (substitution)

Add like terms

21x - 4 = 122

21x - 4 + 4 = 122 + 4

21x = 126

21x/21 = 126/21

x = 6

✔️m<RSN = 6x

Plug in the value of x

m<RSN = 6(6) = 36°

C. 50%

Step-by-step explanation:

First, find 50% of 87 and add it to find the new price.

87 x 0.5 = 43.5

87 + 43.5 = 130.5

Then, find the percent by doing 130.5 ÷ 87, which is 150%
