Question

Hello, I need help on this :)

Enter a number/answer

What is the measurement of b?

Answer 1

21

Explanation:

The rule for a right triangle is (x^2)x(y^2)=(z^2)

so 20 squared is 400 and 29 squared is 841.

And since the side with the length 29 is the hypotenuse.

It is 400 +
`√(x)` = 841

841-400=441

the square root of 441 is 21

Answer 2

21. use Pythagorean theorem
a squared + b squared = c squared
Fill in the blanks so
20 squared + b squared= 29 squared
then you subtract 29 squared from 20 squared to get an answer and then you square root that to get 21
