Question

Help me with my homework pls :)

Answer 1

That smile tho lol

anywayssssss

b= 16 mm

Explanation:

Pythagorean theorem is a^2 + b^2= c^2, so-

12^2 +b^2= 20^2

144+b^2=400

b^2=400-144

b^2= 256

b= 16

Answer 2

16 mm

Explanation:

A²+B²=C²

12²+x²=20²

144+x²=400

x²=400-144

x²=256

√x = √256

x = 16
