Equations A may be used to determine the lighthouse's height. The best choice is A.

<h3>What is the triangle?</h3>

A triangle is a three-sided polygon. It is one of the most fundamental geometric forms.

Given;

(d) 115 meters separate the boat from the lighthouse.

42" is the angle of elevation.

Height is h

Apply the tangent formula in the obtained triangle;

\rm tanx^0= \rm \frac{y}{115} \\\\ tan 42''=\frac{y}{115}

The calculations will determine the lighthouse's height as;

\rm tan 42''=\frac{y}{115}

Hence the best choice is A.

-3x+18=7x what could you do to isolate the variable term to one side of the equation
Alexxandr [17]

Answer:

7x=−x+24 7 x = − x + 24  

Step-by-step explanation:

The equations we solved in the last section simplified nicely so that we could use the. Our strategy will involve choosing one side of the equation to be the variable side, and step by step, to isolate the variable terms on one side of the equation

Prove that an integer consisting of 3n ones is divisible by 3n (e.g. 111 is divisible by 3, 111,111,111 is divisible by 9, etc.)
mote1985 [20]

For proof of 3 divisibility, abc is a divisible by 3 if the sum of abc (a + b + c) is a multiple of 3.

<h3>Integers divisible by 3</h3>

The proof for divisibility of 3 implies that an integer is divisible by 3 if the sum of the digits is a multiple of 3.

<h3>Proof for the divisibility</h3>

111 = 1 + 1 + 1 = 3  (the sum is multiple of 3 = 3 x 1)  (111/3 = 37)

222 = 2 + 2 + 2 = 6 (the sum is multiple of 3 = 3 x 2)  (222/3 = 74)

213 = 2 + 1 + 3 = 6 ( (the sum is multiple of 3 = 3 x 2)  (213/3 = 71)

27 = 2 + 7 = 9  (the sum is multiple of 3 = 3 x 3)  (27/3 = 9)

Thus, abc is a divisible by 3 if the sum of abc (a + b + c) is a multiple of 3.
