Question

Anyone know? its due tonight​

Answer 1

hey mate here is your answer...

Explanation:

by using Pythagoras theorem...

BC² = BD² + DC²

10² = 8² + DC²

DC² = 100 - 64

DC² = 36

DC = 6

DC is the half of AC.

Therefore AC = 12 centimetres.

hope it helps you ❣️

Answer 2

12 cm

Explanation:

Well first we can cut the triangle in half and use the Pythagorean theorm

a^2+b^2=c^2

In this case we are going to be doing c^2-a^2=b^2

10^2-8^2=b^2

(10*10)-(8*8)=b^2

100-64=b^2

36=b^2

Now we just square root 36 (what number times itself is 36)

`√(36)`

b=6

Since half of the one side equals 6 (DC) then the length of AC is 12!
