Answer:

b=21

Explanation:

a^2 + b^2 = c^2

20^2 +b^2 = 29^2

b^2+400=841

b^2=441

b=21 or b= - 21

Since we are using the values for a triangle we take the positive value.

Answer:

21

Explanation:

Use Pythagorean Theorem

If you are looking for leg given the other sides of the right triangle: just do bigger square minus small square

and take square root

so 29^2 - 20^2

And then sqrt it!

sqrt(29^2-20^2)
