Question

BC is 32 cm long and AB is 15 cm long. Find the distance from A to C.

Answer 1

Answer:

AC ≈ 35.3 cm

Step-by-step explanation:

Δ ABC is a right triangle

Using Pythagoras' identity in the right triangle

AC² = BC² + AB² = 32² + 15² = 1024 + 225 = 1249 ( take square root of both sides )

AC = $\sqrt{1249}$ ≈ 35.3 cm ( to 1 dec. place )
