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 
. 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 
.
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.
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.
96 divided by 3 is 32
Therefor, it is divisible by 3

are there any instructions on rounding it to the nearest tenth, hundredths, etc.?
Answer: = 0.198
Step-by-step explanation:
0.60 * (100% + 33%) = 0.60 * 133% = 0.60 * 1.33 = 0.798
The markup is 0.798 - 0.60 = 0.198, which is also 0.60 * 33% = 0.60 * .33 = 0.198
Answer:
Step-by-step explanation:
(a+b)² = a² + 2ab + b²
The only choice that has the form a² + 2ab + b² is D.
