How do you find the value of x and the unknown angle measures?

Question

in 8th grade math, how do you find the answer to x and the unknown angle measures in a quadrilateral

if my angles are 108 degrees (5x+27)degrees,(4x+3)degrees, and 69 degrees how do you find the value of x and the unknown angle measures?

Answer 1

Well, you kind of need to give us the actual problem. But I can give you some basics. The interior angle of a quadrilateral all add up to 360 degrees. So if you have one angle, the angle that is diagonal and opposite of it will be the same angle. Then you add those 2 angles up, subtract them from 360, divide that answer by 2 and that is what the other 2 angles are. So if you are given an angle that is 40, then the angle diagonally from it it also 40. Multiple 40 by 2 and you get 80. Now subtract 80 from 360 and you get 280. Divide 280 by 2 and you get 140. 140 is your answer for the other 2 angles. I hope that made sense. My daughter is in the 8th grade and she said it did. haha Good luck!

Answer 2

well we r gonna needa kno the demensions first

im in 8th grade 2

only im in geometry

so giv me the demensions and i can figure it out

or tell u

(pleez put me as best answer!!!)
