Answer:

a=5

Explanation:

Pythagorean theorem


a^(2) +
b^(2) =
c^(2)

substitute your values


a^(2) +
12^(2) =
13^(2)

- 12 - 12


a^(2) =
13^(2) -
12^(2)

a = 169-144

a= 25

now find the square root of 25, which is 5

Answer: a=5

Step-by-step explanation: Use the pythagorean theorem and get

(a)^2+(12)^2=(13)^2

This would then be (a)^2+144=169

subtract 144 from both sides and get

(a)^2=25

Take the square root of both sides and you get a=5
