The height of the lighthouse is 44 feet.

<u>Step-by-step explanation:</u>

You are given more information than you need.

Use the right triangle concept,

A yacht is anchored 90 feet offshore from the base of a lighthouse.

Base = 90 feet
Height = h feet

The angle of elevation from the boat to the top of the lighthouse is 26 degrees.

<u>Using one side length and the angle only: </u>

The trigonometric formula is given as,

tan = height / base

tan[26º] = h ⁄ 90

h = 90 × tan[26º]

h = 43.9 ft

h = 44 feet

Therefore, the height of the lighthouse is 44 feet.

A rectangular field has dimension of 91 feet by 60 and 1/3 feet what is the area of the field

Oliga [24]

Answer:

Area = $91*\frac{181}{3}=5490\frac{1}{3}$ square feet

Step-by-step explanation:

The area of a rectangle is given by the formula:

A = length * width

Where length is 91 feet and width is $60\frac{1}{3}$ feet

Before we do the multiplication, we have to change the mixed number [width] into an improper fraction by using the rule shown below:

$a\frac{b}{c}=\frac{(a*c)+b}{c}$

Hence,

$60\frac{1}{3}=\frac{181}{3}$

So, the area is:

Area = $91*\frac{181}{3}=5490\frac{1}{3}$ square feet
