29 percent = 29/100
So 29/100 x 20
= 5.8
X = 90 degrees
angle B = 47 degrees
add them together = 137
subtract from 180 = 43
y = 43 degrees
Need to repost. We can’t see the equation
Here, I'll use C for combinations.
There are 15 boys and you need 3 so 15 C 3 ways
There are 30 girls and you need 7 so 30 C 7
and there are 45 total and you need 10 so 45 C 10
The answer is [15 C 3 • 30 C 7] over 45 C 10
so do that on your calculator if you need an actual decimal.
