There are 4 proofs and statements please give them. If you aren't sure please don't answer. Given AC=BD, and AB and CD bisect each other. Prove: <A= <B

Step-by-step explanation:

Given: O is mid point of AB and CD

∴ AO=OB and CO=OD

To prove: AC=BD

Proof: Consider △AOC and △BOD

AO=OB (given)

CO=OD (Given)

∠AOC=∠BOD (Vertically Opposite angle)

△AOC≡△BOD

Hece we get, AC=BD (by c.p.c.t.)

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

i dont know sorry
