Jenn wants to measure the height of a tree. She walks exactly 125 feet from the base of the
nasty-shy [4]

Answer:

81.2\:\mathrm{ft}

Step-by-step explanation:

We can form a right triangle and use basic trig for a right triangle to solve this problem:

\tan33^{\circ}=\frac{h}{125}, where h is the height of the tree.

Solving, we get:

h=125\cdot \tan 33^{\circ},\\h\approx \fbox{$81.2\:\mathrm{ft}$}.

of the students in Ms. Danver's class, 6 walk to school. This represents 30% of her students.How many students are in Ms. Danver

Please help me find out the process to find y for the first three questions and tell me what y is
Sliva [168]

Answer:

1. y = 14.718

2. ??

3. y = 39.794°

Step-by-step explanation:

<em>HINT the side we already know and the side we are trying to find, we use the first letters of their names and the phrase "SOHCAHTOA" to decide which function: </em>

SOH...

 Sine: sin(θ) = Opposite / Hypotenuse

...CAH...

 Cosine: cos(θ) = Adjacent / Hypotenuse

...TOA

 Tangent: tan(θ) = Opposite / Adjacent

1. Sine: sin(θ) = Opposite / Hypotenuse

sin(42°) = y / 22

so on your calculator enter 42 then sin = 0.669

0.669 = y/22      multiply both sides by 22 to get y

y = 14.718

2. is there any other information??

3. The two sides we know are Opposite 40 and Adjacent 48.

SOHCAHTOA tells us we must use Tangent.

Calculate Opposite/Adjacent = 40/48 = 0.833

Find the angle from your calculator using tan-1

Tan y° = opposite/adjacent = 40/48 = 0.833  

tan-1 of 0.833 = 39.794°

Point N is located at (-2, 4) on the coordinate plane. Point N is reflected over the y
Alona [7]

Answer:

(2,4)

Step-by-step explanation:

It's reflected over the y axis so it would still have the same y value but the x value will be positive instead of negative

The point is (2,4)
