Answers:
(x+2) = 55 degrees
x = 53 degrees
the given is 72 degrees
Explanation:
A triangle always equals 180 degrees. It was given that one of the angle measures is 72 degrees. 180-72=108. Now I need to find the value of x. (x+2)+x=108. Solving this equation I get x=53. Substitute this back into the angle measures and u get the answers as stated above.
The first number is coefficient for i, and the second number is coeff. for j
=>
<0,-8> is the same as 0i-8j, or simply 8j
1st one: linear
2nd one: linear
3rd one: nonlinear
Improper because the top is supposed to be lower than the bottom
