Answer:

A = 14.8 B = 14.8

Explanation

What you do first is you use the pythagorean theorem to write out the equation

a^2 + b^2 = c^2

a^2 + b^2 = 21^2

a^2 + b^2 = 441

i couldnt find any whole numbers to fit in this equation so just divide 441 by 2

and get the square root of 220.5 which is 14.8 to the nearest tenth for both a and c
