The ladder , ground and the building form a right angled triangle
The angle that ladder makes with the building is 90-47 = 43 degrees Answer.
The answer should be y=x-2. To solve other questions like these, find the y-intercept on the y-axis and use rise over run to count the slope between the points. Here it rises 3 and runs 3, simplifying to one. The y-axis crosses at -2. Plug this into y=mx+b and you get y=x-2
Answer:
