I struggle with proofs too! They're the worst.

l is parallel to n because of the parallel lines theorum,.
∠3≅∠4 becasue converse of alt. interior angles
∠1≅∠2 because converse of alt. interior angles
not sure about the last one but i tink its m ║ n
PLEASE MARK BRAINLIEST
Since AO is parallel to CD, the angles CAB and BCA will be congruent. Therefore they both equal 57. that gets you on the right track
Answer:
Door 2
Step-by-step explanation:
To do this problem, we need to use the Pythagorean Theorem. The door is a rectangle and if we draw a line from corner to corner, we have right triangles.
To find the diagonal distance, we have to write and solve the equation below.
3^2 + 9^2 = c^2
9 + 81 = c^2
90 = c^2
c = the square root of 90
The square root of 90 can be simplified to 3 square roots of 10.
