Answer:
see below
Step-by-step explanation:
The sides of the triangle that are given in relation to x are the Adjacent side (10) and the Hypotenuse (15). The mnemonic SOH CAH TOA tells you the trig function that uses sides A and H is the Cosine function.
Cos = Adjacent/Hypotenuse
cos(x) = 10/15

(4x)^2=4x times 4x
4x^2=4 times x times x=4(x^2)
(4x)^2=16x^2
4x^2=4(x^2)
values are not equal
(just for fun: 4x^2=(2x)^2)
A(0,0) A'(2,1)
distance(AA') = √(2^2 + 1^2)
= √5
= 2.24
answer
Distance AA' = √5 or = 2.24
Answer: 
Step-by-step explanation:
125/21 = 150/x
cross multiply
125x = 3150
x = 3150/125
x = 25.2 lbs....rounded up = 26 lbs <==
