Pythagorean Theorem.

Answer 1

Answer:

a = 21

Step-by-step explanation:

a = sqrt(c^2﹣b^2)

= sqrt(29^2﹣20^2)

= 21

Answer 2

Answer:

a = 21

Step-by-step explanation:

The Pythagorean Theorem is a² + b² = c²

So solving for a would give us $a=\sqrt{c^{2}-b^{2} }$

Now plugging in our values we get $a=\sqrt{(29)^{2}-(20)^{2} }=\sqrt{841-400}=\sqrt{441}=21$

a = 21
