Find the value of each variable in the parallelogram

wlad13 [49]

Answer:

B= 90

C= 80

D= 100

Step-by-step explanation:

So let’s start with the bottom angles.

We know that the adjacent angles in a parallelogram add up to 180° so our equation would be $(b-10) + (b+10)=180$ . So let’s simplify it b and b are both the same variables so we will get 2b and -10 + 10 is 0 so we get the following equation $2b=180$ .

So now we divide 180 and 2 and we get 90 as b.

So one side will be 100 because of the +10 and the other 90 because of the -10.

Now for the next side.

$d+c=180$

So we know that b+10 is adjacent to c so 180-100 is 80, so 80 is c.

Now for d.

b-10 is 80 so 180-80 is 100, so d is 100.
