Question

What is the measure of SRT?
R
S
53°
48°
[Not drawn to scale]
T

Answer 1

B) 79°

Explanation:

All interior angles of a circle add up to 180°.

We have 2 angles 53° and 48°, so we can write an equation:

53+48+x=180

simplify

101+x=180

subtract both sides by 101

x=79

So, the measure of angle SRT is 79°
