What is the measure of angle A ?
what is the measure of angle B ?

Step-by-step explanation:

Notice that buy construction of a parallelogram,the angles and must equal each other. Then, based on the info given,  we can write the following equation:

Then, angle =  which is also equal to angle B

and since the addition of all internal angles of the parallelogram must equal , then:

and therefore, since and  must be equal, then:

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.

i think the answer is b.

step-by-step explanation:

not 100% sure though.
