Question

What is the length of BC?
Helppp​

Answer 1

8
`√(2)`

Explanation:

Actually, when you look at it, it' very simple.

So as you kno triangles always = 180

That makes this way easier when you think about it

Let's add the angels together

90+45= 135

Now we need to find the value of the missing angle

180-135= 45

So 45 is the missing angle

Since m∠C≈m∠B he side length (AB) is also 8

Now we can find the length of the hypotenuse

`√(a^2 +b^2)`

a and b are the side lengths so just plug them in

`√(8^2 + 8^2)`

Now you solve

Exact Form: 8
`√(2)`

Decimal Form: 11.31
