Given a right triangle with legs a, b and hypotenuse c, solve for a if b= 20 and c= 29

a 35.2

b 3

c 21

d 9

C) 21

Step-by-step explanation:

a² + 20² = 29²       Use Pythagorean Theorem to solve for a

a² + 400 = 841       Solve for the exponents

     - 400 - 400      Subtract 400 from both sides

a² = 441                  Take the square root of both sides

a = 21

y > 1/3x

y < = -x + 4
