Find the error solving for x​

You weren't supposed to equal 115 to 5x-10 you have to use distribution for 115(5x-10) and then set it equal to 180 which is the total degree of both angles.

Step-by-step explanation:

you were supposed to add and equate to 180

115+5x-10=180

5x+105=180

5x=180-105

5x=75

x=75/5=15

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
