The angle of elevation from a buoy in the water to the top of a lighthouse is 68degrees. If a buoy is 300 ft from the base of th
Katen [24]

Answer:

The height of the lighthouse is 742.5\ ft

Step-by-step explanation:

Let

h -----> the height of the lighthouse

we know that

The tangent of angle of 68 degrees is equal to divide the height of the lighthouse by the horizontal distance from the buoy to the base of lighthouse

so

tan(68\°)=\frac{h}{300}

Solve for h

h=(300)tan(68\°)=742.5\ ft

2m+(m-15)=90 solve for m
Ronch [10]

Answer:

m = 35

Step-by-step explanation:

2m + m -15 = 90

3m -15 = 90

     +15  +15

3m = 105

/3     /3

m = 35

To check the work just insert 35 for m:

2(35) + 35 -15 = 90

70 + 35 -15 = 90

105 - 15 = 90

90 = 90

In the following equation, when x=0, what is the value of y?<br><br> 3x + 4y = 12
iren2701 [21]

Answer:

(3)(0)+4y=12

Step 1: Simplify both sides of the equation.

(3)(0)+4y=12

0+4y=12

(4y)+(0)=12(Combine Like Terms)

4y=12

4y=12

Step 2: Divide both sides by 4.

4y

4

=

12

4

y=3
