18+x+x=180
180-18=162
162/2=81
X=81
Triangles always have a total of 180 degrees and the angles have the same variable which means they are the same number.

Answer:
10 prob?
Step-by-step explanation:
A) the x-values on the graph are [-2, 4].
all the x-values of the graph are the Domain of the function of the graph. they are found by projecting the graph to the x-axis. check the yellow line in the first picture.
b) all the possible outputs of g are [-1, 3].
all the possible outputs of g, are the Range of g. These are found by projecting the graph to the y-axis. check the red line in the second picture.
c) -1 , 0, 1, 2, and 3 are only a few values in the Range. The range is [-1, 3].
d) we will sketch a graph whose domain is [-2, 4] and range is [-1, 3]. check picture 3
