Answer:
Yes, it does represent a proportional relationship.
You can see that for every given value of x, the corresponding value of y is twice as much. That means that the first answer is correct; the values are proportional, and the ratio is 2.
Solution:
(tanx + tany)/(1-tanxtany) is equal to the formula of tan(x+y)
sinxcosy + cosxsiny = is equal to the formula of sin(x+y)formula
cosxcosy - sinxsiny) = is equal to the formula of cos(x+y)
So this means that
tan(x+y) = sin(x+y)/cos(x+y)
Answer:Let
x-----------> the number
we know that
The expression "the difference between five times a number and twice that number" is equal to
5x-2x
therefore
the answer is
5x-2x

The measure of the angle of elevation from the ground to the top of the ladder is 68.73 degrees
<h3>Angle of elevation and depression</h3>
These method is used to determine the side and angles of a triangle
From the question given, we have the following parameters
Base of the building = 7feet (Adjacent side)
Height of the building = 18 feet (Opposite side)
Required
angle of elevation of the building
Using the SOH CAH TOA identity
tanФ = opp/adj
tanФ = 18/7
Ф = 68.73 degrees
Hence the measure of the angle of elevation from the ground to the top of the ladder is 68.73 degrees
