Question

The diagram shows a triangle ABC in which AB= 6 cm, BC=8 cm and ABC = 90°.

Calculate the length of AC.

The answer should be 12. please help with explanation and calculation!!!

Answer 1

AC = 10

Explanation:

This is a right triangle

use the pythagorean theorem

a² + b² = c²

6² + 8² = c²

36 + 64 = c²

100 = c²

Take the square root of both sides

10 = c

AC = 10

The correct answer is 10 not 12
