Answer:
x = 3
Step-by-step explanation:
both angles together equal 180
Set your formula as
180 = 5x + 165
180 - 165 = 5x
15 = 5x
15/5 = x
3 = x
Since we know that squares have the same length on all sides, you would find the square root of 170
√170=13.03840481
rounded to the nearest tenth would be 13.1
You can check your work by multiplying 13.1 by 13.1 which equals 170.3
I try to explain the problem and give the answer, I hope this helps!
The area is 25
a= 1/2bh
=1/2(10)(5)
=1/2(50)
Because 50% of something means half (because 100-50=50), he would have to make the number of girls and boys equal. Since there are 21 girls, he has to make it so there are also 21 boys.
So, if we know that 21-15=6, this means he would have to add 6 boys to the club if he wants the girls and boys equal.
