In order to find the length of ?? (let's call this distance x), let's first find the value of Angle A.
The cosin of Angle A is Adjacent / Hypotenuse, or 40 / 50. Using this Info:
cos (A) = 40/50
cos (A) = .8
With this crucial piece of info, we can find the Total length of A-D (Point D being the point above C), by finding its relation to side AC (length of 50 + 70 =120 ft)
Cos (A) = adjacent / hypotenuse
Cos (A) = AD / (120) We know that cos (A) = .8
.8 = AD / (120) Multiply both sides by 120
96 = AD
We're almost there! Remember that we're trying the find x (?? in the diagram).
x + 40 = 96
x = 56 ft
For each inequality, multiply the individual fractions to get the same denominator. Then you can just compare the numerators.
For example:
5/8<2/3
15/25<16/24 is true
Answer:
See below
Step-by-step explanation:
Expand it a bit to see:
= ![\sqrt[5]{ 2^5 * 7 * x^5 * x^5 * x * y^5 * y^3}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7B%202%5E5%20%2A%207%20%2A%20x%5E5%20%2A%20x%5E5%20%2A%20x%20%2A%20y%5E5%20%2A%20y%5E3%7D)
=![2x^2y \sqrt[5]{7xy^3}](https://tex.z-dn.net/?f=2x%5E2y%20%5Csqrt%5B5%5D%7B7xy%5E3%7D)
