Question

What does 2+2 equal

Answer 1

Answer: 14.4

Step-by-step explanation: To find the third side of the triangle, we have to  use the pythagorean theorem...

a² + b² = c²

a² + 4² = 15²

a² + 16 = 225

225 - 16 = 209

$\sqrt{209}$

a ≈ 14.4 (If rounded it would be 14)

I hope this helps!

Answer 2

2+2=4

a^2+b^2=c^2
15^2-4^2
=225-16
=209
