Answer: The distance is 335.88 feet away from the building.

Step-by-step explanation:

Suppose we have a triangle rectangle, where we know that one of the cathetus is equal to 90 ft, the opposite angle to that side is equal to 15° (the maximum angle that the stand can be tilted)

Now we want to know the value of the other cathetus, the adjacent to the angle.

By trigonometry, we know that  

Tan(θ) = (opposite cathetus)/(adjacent cathetus)

then:

tg(15°) = 90ft/X

X = 90ft/Tg(15°) = 335.88 ft

Your friend says that 14.5% is same as the fraction 29/200. explain whether your friend is correct or incorrect by comparing the
OlgaM077 [116]

14.5% = 0.145

Step-by-step explanation:

The term 'percent' (%) actually means per 100. So when you say 14.5% it means 14.5 per 100. So when you put that into an equation it actually means:

So when you solve it, 14.5% is actually 0.145 and not 14.5.

Your friend is then incorrect because:

14.5% ≠ 14.5

4x-5=2x+7 midpoint segmen
Bogdan [553]

Answer:

x = 6

Step-by-step explanation:

The way to solve this is by subtracting 2x from both sides. Now we have

2x-5=7

Then we add 5 from both sides. Now we have

2x=12

We do this because we want X by itself

Then we divide by 2 on both sides and now we have

x = 6
