If ΔABC is a right angled triangle with ∠ABC = 90o, and AC = 10 cm, BC = 8 cm, then the length of AB is:
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 6 cm.
| Understanding/Application |
|
Since ABC is a right-angled triangle - Applying Pythagoras theorem - AC2 = AB2 + BC2 (10)2 = AB2 + 82 |
|
100 = AB2 + 64 AB2 = 36 AB = 6 cm |
