Question

What’s the answer xx

Answer 1

Explanation:

Hey there!

Given;

ABC is a Right angled triangle.

Taking angle "A" as reference angle, we get;

Perpendicular (p) = BC

hypotenuse (h) = 13cm

Base(b) = 8cm

We know;

`{h}^(2) = {p}^(2) + {b}^(2)`

`or; \: p(BC) = \sqrt{ {h}^(2) - {b}^(2) }`

`BC = \sqrt{ {13}^(2) - {8}^(2) }`

`BC = √(169 - 64)`

`BC = √(105)`

`BC = 10.246`

Therefore, BC = 10.246cm.

Hope it helps...
