The sum of the angle measures of a quadrilateral is 360°. Write and solve an equation to find the value of . 76°
to
122°
92°
The equation is
360

let the unknown no.be x

therefore, 76+122+92+x = 360

                 = 198+92+x = 360

                = 290+x = 360

                    x=360-290

                    x= 70degree

hope this is helpful,

step-by-step explanation:

question: match the eqaution with its graph -8x - 5y = 40

answer: 8 x 5 = 40

x= absiss

y= orderly

so you have a proportional graph
