The people of Bridgetown wanted to build a bridge across a nearby river. Since they were poor swimmers, their master Trigonomos
VikaD [51]

Answer:

60.2 m

Step-by-step explanation:

Let x represent the width of the river.  The distance from the point across from the tree to the second point is 15 m.  The angle from this point to the tree across the river is 76°.

This makes the side opposite the angle x, the width of the river.  It also means the 15 m side is adjacent to this angle.

The ratio opposite/adjacent is the ratio for tangent; this gives us the equation

x/15 = tan(76)

Multiply both sides by 15:

15(x/15) = 15(tan(76))

x = 15(tan(76)) ≈ 60.2

A parking garage has 500 parking spaces. One morning 330 parking spots were filled. What percent of the parking spaces were fill
blondinia [14]
Hey there! :D

So, what we need to do is make a fraction that has a denominator of 100. This is the simplest route to take.

330/500

If you took one zero away from each side, you will get an equivalent fraction:

33/50

Multiply both side by 2 to get to 100.

33*2=66 50*2=100

66/100

So, 66% percent ornament the parking lots were filled.

I hope this helps!
