Answer:

a = 11 2/3

Step-by-step explanation:

The pythagorean theorem is a^2+b^2=c^2.

We are given the value of b and c.

a^2 + 4^2 = 12 1/3^2 (Substitute the numbers into the variables)

a^2 + 16 = 152 1/9 (Square the numbers)

a^2 = 136 1/9

a^2 = 11 2/3 (Find the square root)

Find Square Root:

136 1/9 = 1225/9

(√136 1/9) = (√1225)/(√9)

35/(√9) (Find square root of 1225)

35/3 (Find square root of 9)

35/3 = 11 2/3 (Simplify)

Hoped I've helped! Good Luck!
