Question

OMG I REALLY DONT UNDERSTAND... In parallelogram ABCD, angle A is 5x + 2 and angle B is 108° Plzzz explain to me

Answer 1

in any parallelogram, the adjacent angles are supplementary

this means that they add to 180 degrees

Answer 2

So

A+B = 180

(5x+2) + (108) = 180

5x + 2 + 108 = 180

....
....

x = ??

Answer 3

14?

Answer 4

and if x = 14, then

A = 5x + 2

A = 5*14 + 2

A = ??

Answer 5

72?

Answer 6

good, so A = 72, B = 108

C = 72 (since C is opposite A)

D = 108 (D is opposite B)

Answer 7

thanks :)
