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.
Answer:
16 and 17
Step-by-step explanation:
16 * 17 = 272
The experimental probability of the computer generating a 2 is 20%.
<h3>What is the experimental probability?</h3>
The experimental probability determines the odds an event would happen based on the results of an experiment.
Experimental probability = ( number of times a 2 was generated / total number of numbers generated) x 100
(16 / 80) x 100 = 20%
