Question

find the values of a & b that would make the quadrilateral a parallelogram (pic shown)

Answer 1

in an parallelogram opposite angles are equal
5b+6=8a-10
and adjacent angles adds up to 90
(4a-8)+(8a-10)=90
now you have the two equations to solve for a and b

Answer 2

ohhh okay. i knew those two had to equal each other.. my answer just never made sense! thanks !

Answer 3

so you got it?

Answer 4

(4a-8)+(8a-10)=180?

Answer 5

the answer i got was different than the back of the book :/

Answer 6

try with
5b+6=8a-10
(4a-8)+(8a-10)=180

Answer 7

now i got the right answer! thanks!

Answer 8

oh yeah im so sorry i made a mistake they should add up to 180 and not 90.

Answer 9

its fine :) but thanks again
