Question

(HELP!!) Find the values of a and b for which LMNO is a parallelogram.

A.a = 50, b = 60
B.a = 60, b = 50
C.a = 50, b = 70
D.a = 70, b = 50

Answer 1

HINT: opposite sides of parallelogram are equal

Answer 2

so,
\[\huge b+20=2b-50\]
solve for b???

Answer 3

a+40=2a-10
-40 -40
______________
a=2a-30 ?

Answer 4

b=2b-30

Answer 5

this looks like the same as your last question, with different numbers

Answer 6

still confused on it. :/

Answer 7

\[\huge a+40=2a-10\]
\[\huge -a=-50\]
\[\huge a=50~degree\]

Answer 8

b=60

Answer 9

So the answer is A?

Answer 10

just remember that opposite sides are equal in a parallelogram, set them equal to each other to find the variable

Answer 11

no!!!

Answer 12

b=70

Answer 13

it should be correct?

Answer 14

you are right
