Question

A, B & C form a triangle where ∠ BAC = 90°. AB = 14.4 mm and CA = 14.2 mm. Find the length of BC, giving your answer rounded to 1 DP.

Answer 1

Answer:

Answer:

The length of BC would be 12.2 mm.

Step-by-step explanation:

Given,

In triangle ABC,

∠BAC = 90°,

Thus by the Pythagoras theorem,

We have,

AB = 9.6 mm and CA = 7.6 mm,

By substituting the values,
