What is x please help

x = 71

Step-by-step explanation:

Given the triangle in red, we can find the unknown angle since the sum of the angles of a triangle are 180.  Call the unknown angle GHI

B+ D+ GHI = 180

31+ 40 + GHI = 180

71 + GHI = 180

GHI = 180 -71

GHI = 109

We know that GHI + x = 180 since it forms a straight line

GHI + x =180

109 + x = 180

x = 180-109

x = 71

17 1/3

step-by-step explanation:

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
