A triangle has two angles that have measures of 92° and 31°. What is the measure of the third angle of the triangle? A 23
B 57
C 43
C 33

57⁰

Step-by-step explanation:

A triangle measures 180⁰, so to find the answer to these questions you just have to add the degrees you know

92⁰+31⁰=123⁰

after you take 180⁰ and subtract the degrees you know your triangle has

180⁰-123⁰= 57⁰

the final function for the graph becomes x-2=-1. before graphing you solve the equation, where x=1. then graph accordingly.   ( on the x-axis, 1 on the line will possess a vertical line.)
