Question

7. In a right angles triangle ABC, ZB = 90°, AC = 10 cm and AB = 8 cm find the length of BC.​

Answer 1

Answer: Length of BC will be 6cm.

Step-by-step explanation:

This question is solved using the Pythagoras theorem, which states that height²+base²=hypothenuse². in this case, AB can be the height, BC can be the base, and AC is the hypothenuse.

1. height²+base²=hypothenuse²
2. AB²+BC²=AC²
3. (8cm)²+BC²=(10cm)²
4. 64cm²+BC²=100cm²
5. BC²=100cm²-64cm²=36cm²
6. BC²=36cm²
7. BC=√36cm²
8. BC=6cm

Given above is the way to solve this. Hope it helps
