Answer:

The distance from point A to the top of the building is 5\sqrt{2} feet

The Height of the Skyscraper is 5 feet

Step-by-step explanation:

Given

Let Top point of building be point C

Also Let Base of the building be point  B

Distance from point A to base B of the building AB= 5 feet

∴ It makes a Right angle triangle

Also ∠ACB = 45°

Also tan 45° = 1

Now tan ∠ACB =\frac{AB}{BC}

∴ AB= BC =5 feet

The Height of the Skyscraper is 5 feet

Now Triangle ABC is right angle triangle with right angled at B

So by Pythagoras theorem

AC= \sqrt{AB^2+BC^2}=\sqrt{5^2+5^2} =\sqrt{50} =\sqrt{25\times2} =\sqrt{5^2\times2}=5\sqrt{2}

The distance from point A to the top of the building is 5\sqrt{2} feet

natali 33 [55]

Answer:

$333.33

Step-by-step explanation:

This question is a little bit confusing, but I am assuming you mean to say that the 72% of the total pay, which is the amount he took home, is $240. So, then you can set up a proportion to solve the problem.


72\frac{72}{100} = \frac{240}{x}

Then, you multiply the proportion out, getting 72x = 240*100

multiply the right side out and then divide by 72 to get $333.33
