Given the diagram of parallelogram LMNO, solve for s.

A.
20
B.
30
C.
40
D.
120

Answer 1

opposite angles in a parallelogram are equal...

so look at the angles containing t

2t + 10 = 3t - 15

solve for t

then calculate the size of the angle...

does that make sense...?

Answer 2

so i got t=5?

Answer 3

not quite

2t + 10 = 3t - 15
+15 +15
----------------
2t + 25 = 3t
-2t -2t
-------------



what is the value of t..?

Answer 4

25=t

Answer 5

great... so what is the size of angle O..?

Answer 6

25 but i need to find s

Answer 7

just a minute... what is the size of angle O..?

2t + 10 = when t = 25

Answer 8

so its 60

Answer 9

great... so the shape is a parallelogram

that means angles O and L are co-interior...

does that help you find s...?

Answer 10

so its 120?

Answer 11

the answer?

Answer 12

great angle L = 120 so angle N = 120

so now you can find s

Answer 13

no ideal?
what do i do?

Answer 14

because there is a 3s

Answer 15

well angle N has a measure of 120

and it showns angle N is also 3s

so equating them

3s = 120

can you solve for s

Answer 16

oh 120/3

Answer 17

you think you can help me with one more?
