Question

∆ ABC is right-angled at C. If AC = 5 cm and BC = 12 cm find the length of

AB.

Pls send correct answer​

Answer 1

Answer:

1. by PGT theorem
2. AB^2 +BC^2=AC^2
3. AB^2+12^2 =5^2
4. AB^2 +144 =25
5. AB^2=144-25
6. AB^2 = 119
7. AB =√119

Answer 2

Step-by-step explanation:

according to Pythagoras theorem

ac² + ab² = bc²

5² + ab² = 12²

25 + ab² = 144

ab² = 144 - 25

ab² = 119

ab = √119

or ab = 10.908
