Question

Please Help!
Calculate the side lengths a and b to two decimal places.

A. a = 11.08 and b = 13.54
B. a = 11.08 and b = 12.94
C. a = 6.37 and b = 5.45
D. a = 12.94 and b = 11.08
E. a = 5.45 and b = 6.37

Answer 1

There are multiple ways to do this problem, but one way is to just split up that bottom side into two parts and try to find the height of the triangle like this:



You now have two equations and two unknowns. After that, you can solve for a and b with they pythagorean theorem.

Answer 2

y/x=8.3308 and y/(8.4-x)=0.329 ?

Answer 3

did i do it correctly?

Answer 6

Sure, you're getting there, but you need to solve for things you can work with. You know how to use the pythagorean theorem right? So by making a right triangle here:



You're able to find a by looking at x^2+y^2=a^2 and do something similar with (8.4-x)^2+y^2=b^2. Think about this and explain to me where everything is coming from to help me help you understand where I invented this stuff.
