To find out how high Juanisha climbed in problem 4-56, you need to know more about the relationship between the ratios of the sides of a right triangle and the slope angle. Use two different strategies to determine Δyfor the slope triangles shown in the diagram at right.

if im not mistaking its

step-by-step explanation:  

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
