Question

In triangle ABC, angle C is a right angle. If AC=15 and CB=36, find AB?

Answer 1

AC=15

CB=36

<C=90degrees

using pythagorean theorem

the hypotenus or AB = rootof{(CB^2)+(AC^2)}

the above eq is only applicable to right angle triangles (one angle is a right angle).

Answer 2

AB, the hypotenuse, is 39.  

Answer 3

AB is hypotenuse

AB² = AC² + BC²

= 15² + 36² = 1521

AB = √1521 = 39
