Question

What is the answer to this

Answer 1

a^2 + b^2 = c^2

5^2 + 12^2 = c^2

25+144= c^2

(radical over 169) = (radical over c^2)

13=c

Answer 2

13

Explanation:

Use Pythagoras

c^2 = a^2 + b^2

• a = 5
• b = 12
• c = ?

Solution

c^2 = 5^2 + 12^2

c^2 = 25 + 144

c^2 = 169

Take the square root of both sides.

sqrt(c^2) = sqrt(169)

c = 13
