In a right triangle ABC, angle B is 90 degrees and AB = 12cm and BC = 5 cm. Find the value of AC.(a) 12 cm(b) 15 cm(c) 13 cm(d)14 cm
Given: A right angle ABC such that angle B is 90 degrees and AB = 12cm and BC = 5 cm.
To find: We have to find the value of AC.
Solution:
Now using Pythagoras theorem:
AC2 = AB2 + BC2
AC2 = 122 + 52
AC2 = 144 + 25
AC2 = 169
AC = √169
