Please help me solve this equation. I need it ASAP! I included the question, and options for answers. Each step needs to have its own rule which I also included a picture of.

Two streets intersect at a 30- degree angle. at the intersection, the are four crosswalks formed that are the same length. what type of quadrilateral is formed by the crosswalks?

If the scale factor between two circles is 2x/5y what is the ratio of their areas?

Aladder that is 20ft long is leaning against the side of a building. if the angle formed between the ladder and the ground is 75 degrees how far is the bottom of the from the base of the building?
