its 29 m

Step-by-step explanation:

as a²= b²+c²

a²=(21)²+(20)²

a²=841

a=√841

a=29

here we need to consider the diagonal angle of the opposite corner that makes up the rectangle so the answer is 29 which is the diagonal length of the rectangle.

for every girl taking classes at the martial arts schools there are 3 boys who are taking classes at the school. if there are 23
Yuliya22 [10]

You have to be very careful how you set this up. For every girl (who counts as 1) there are 3 boys (who count as 3). The total number in the proportion is 3 + 1 =4. You are given a total, but that is both boys and girls. That's why you need the 4.

3/4 = x / 236 Cross multiply

4x = 3 * 236

4x = 708 Divide by 4

x = 708/4

x = 177

There are 177 boys at the school and 236 - 177 = 59 girls.
