Kayson is looking at two buildings, building A and building B, at an angle of elevation of 40°. Building A is 120 feet away, and
Sav [38]

Answer: Choice B

Building A; it is around 50.34 feet taller than building B

======================================================

Explanation:

Draw two right triangles such that they both have a reference angle of 40 degrees. Since it's an angle of elevation, place the angle near the horizontal side.

Opposite each reference angle is the height of the building, which we'll call h.

The adjacent side is the horizontal distance from the person to the building.

Building A is 120 ft away so it's height is...

tan(angle) = opposite/adjacent

tan(40) = h/120

h = 120*tan(40)

h = 100.69

This value is approximate. Make sure your calculator is in degree mode.

-----------------

Repeat the same idea for building B, except the adjacent side is smaller this time.

tan(angle) = opposite/adjacent

tan(40) = h/60

h = 60*tan(40)

h = 50.35

This value is approximate.

-----------------

Now subtract the heights

100.69 - 50.35 = 50.34

This shows that building A is roughly 50.34 taller than building B.

kifflom [539]
If there are 4 ounces of vanilla in a 12 ounces milkshake , it means that every 3 ounces of milkshake , 1 ounce of those 3 ounces is vanilla 4 ÷ 12 = 1/3
1/3 is the proportion of vanilla and milkshake.

4 ÷ 12 can also be written as 2/6 or 4/12

Awnser : 1/3 , 2/6 or 4/12 , 8/24 etc ...

ps. dont drink this milkshake , it is just chocolate and vanilla ( theres not even milk in it )

Pachacha [2.7K]

Answer:

5/2

Step-by-step explanation:

the equatino you are using is point slope form which is an equation involving the points and the slope and the origonal equation is y-y1=m(x-x1) m standing for slope, and x1 and y1 standing for the first coordinates, so the slope would be 5/2

Jackets = 2*49 = 98

She bought 3 sweaters

Sweaters = 3 * 25 = 75

The costs for the jackets and sweaters is 98+75 =173

She spent a total of 185

185-173 = 12

She spent 12 dollars on socks

Socks are 3 dollars each

12/3 = 4

She bought 4 pairs of socks
