What is the value of x?

see below

Step-by-step explanation:

x and 80 are adjacent, supplementary angles

Supplementary angles add to 180

x+80 =180 degrees

Subtract 80 from each side

x+80-80=180-80

x=100

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

step-by-step explanation:

an equation by definition has to have two or more variables (x and 2 in this case)
