The captain of a boat knows that a lighthouse on the coast is 100 ft. tall. If he measures the angle of elevation to be 2 degree

faltersainse [42]

Answer and Step-by-step explanation:

| \

| \

100 ft. | \

| 2 \

|_________\

Use tangent to find the x.

tan(2) = $\frac{100}{x}$

$x = \frac{100}{tan(2)}$

Use a calculator to evaluate.

$x = \frac{100}{tan(2)}$ = 2863.6253

So, the boat is 2,863.63 feet from the shore.

Agata [3.3K]

Answer:

$\frac{5x^{2} }{12}$

Step-by-step explanation:

Given: Height: x

Base: $\frac{5x}{6}$

Now, finding the area of triangle.

Formula; Area of triangle= $\frac{1}{2} \times base\times height$

⇒ Area of triangle= $\frac{1}{2}\times \frac{5x}{6} \times x$

⇒ Area of triangle= $\frac{5x^{2} }{12}$

Hence, area of triangle= $\frac{5x^{2} }{12}$

Which is the most accurate way to estimate 66% of 14?

Svetlanka [38]

Answer:

9.1

Step-by-step explanation:

Typically when a question starts with which that means there are several options to choose from. Or multiple choice. Since you haven't provided that here, I'll tell you how I would estimate it.

50% of 14 is 7

10% of 14 is 1.4

5% of 14 is 1/2 of 10% of 14 which is 0.7

50% + 10% + 5% = 65%

Add them together: 7+1.4+0.7 = 9.1
