Hey there! 

If z = 5 

we replace "z" with "5" 

So, let's test out the problem to see if it is true or false

Problem becomes: 3(5) = 2(5) + 5

Let's work this out

3(5) = 15

Problem becomes: 15 = 2(5) + 5

2(5) = 10

Problem becomes: 15 = 10 + 5

10 + 5 = 15

So, therefore it looks like this statement/ sentence is True!

Ivan

Answer:

In fact, the AB could be calculated in a quickest way, using Pythagorean theorem. In here, we try to use the property of trigonometry to work out AB.

Before applying trigonometry, in this right triangle we can calculate the remaining angle C:

C = 180 - 90 - A = 180 - 90 - 53.13 = 36.87 deg

We can use cosine formula, but here we use the sine formula for the sake of convenience. We have:

sine(angle measure) = ratio of opposite side over hypotenuse

In detail, sineC = AB/BC

Then, we have: AB = BC x sineC = 15 x sin(36.87 deg) = 9.000002 = ~9 ft

Hope this helps!

:)
