While sailing, Jacob is 150 feet from a lighthouse. The angle of elevation from his feet on the boat (at sea level) to the top o
Vlada [557]

Answer:

The height of the lighthouse is approximately 166.6 feet.

Step-by-step explanation:

Let the height of the lighthouse be represented by s, then;

Tan 48° = (opposite) ÷ (adjacent)

Tan 48° = s ÷ 150

⇒ s = 150 × Tan 48°

      = 150 × 1.1106

     = 166.59

s ≅ 166.6 feet

Therefore, the height of the lighthouse is approximately 166.6 feet.

PLEASE HELPPP!!! Which expression is equivalent to sum of quantity negative three and one third times n plus one sixth end quant
uranmaximum [27]

The given expression is equivalent to the expression - 11/6 n - 1/12. Then the correct option is C.

<h3>What is Algebra?</h3>

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

The sum of capacity minus three and one-third times n plus one-sixth ended capacity + capacity one and three-sixths times n minus three-twelfths end quantity.

Let n be the number. Then the expression will be

⇒ -(3  1/3)n + 1/6 + (1  3/6)n - 3/12

Simplify the equation, then we have

⇒ -(3  1/3)n + 1/6 + (1  3/6)n - 3/12

⇒ -10/3 n + 3/2 n + 1/6 - 1/4

⇒ -11/6 n - 1/12

The given expression is equivalent to the expression - 11/6 n - 1/12. Then the correct option is C.
