Answer:
179 ft
Step-by-step explanation:
The applicable trig relation is ...
Tan = Opposite/Adjacent.
The height of the lighthouse is the opposite side of the right triangle. The adjacent side to the angle of elevation from the boat is the distance to the lighthouse base. Then ...
tan(50°) = height/(150 ft)
height = (150 ft)(tan(50°)) ≈ 178.76 ft
The height of the lighthouse is about 179 feet.

hope this helped
Answer:
2 8/9 cups of flour
Step-by-step explanation:
13/3 = flour needed for 3 loaves of bread
13/3 divided by 3 should get you the unit rate
13/3 * 1/3 = 13/9
13/9 is the unit rate. Then, you can multiply by 2
26/9 or 2 8/9 cups of flour

Answer: n=7+1/2
Step-by-step explanation:
We move all terms to the left:
2n+15-(30)=0
We add all the numbers together, and all the variables
2n-15=0
We move all terms containing n to the left, all other terms to the right
2n=15
n=15/2
n=7+1/2

What is the length of the hypotenuse, x, if (12, 35, x) is a Pythagorean triple?
33
37
47
58
Answer: The answer is 37.
Step-by-step explanation: i took test
The length of the hypotenuse, x is 37.
The correct option is B.
What is Pythagoras theorem?In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem.
Given:
A Pythagorean triple (12, 35, x).
Applying the Pythagoras theorem,
The length of the hypotenuse, x,
x = √(35)² + (12)²
x = √1369
x = 37
Therefore, the value of x is 37.

what is the number that is two more than one-tenth of one-fifth of one-tenth of 2,000
Answer:
6
Step-by-step explanation:
2 + (1/10)(1/5)(1/10)2000 = 2 + (1/500)(2000) = 2 + 4 = 6
The number that is two more than one-tenth of one-fifth of one-tenth of 2,000 will be 6.
What are the ratio and proportion?The ratio is the division of two numbers while multiplication is an operation in mathematics to multiply two or more values to get a multiplied number.
Proportion is the relation of a variable with another. It could be direct or inverse.
The one-tenth of x = (1/10)x similarly
one-tenth of one-fifth of one-tenth = (1/10)(1/5)(1/10)
So one-tenth of one-fifth of one-tenth of 2,000 = (1/10)(1/5)(1/10) ×2000
⇒ 2000/500 = 4 Now the question is saying 2 more hence
⇒ 4 + 2 = 6 hence six will be the correct answer.

Answer:
x = 119, y = 55
Answer:
x = 119°
y = 55°
Step-by-step explanation:
y + 125 = 180 {linear pair}
y = 180 - 125
y = 55°
Sum of all the angles of quadrilateral = 360
x + 55 + 72 +114 = 360
x + 241 = 360
x = 360 - 241
x = 119°

If f(x)=-2x+5, find f(4).*
Answer: x=-1/2y+5/2
Step-by-step explanation:
Step 1: Flip the equation.
−2x+5=y
Step 2: Add -5 to both sides.
−2x+5+−5=y+−5
−2x=y−5
Step 3: Divide both sides by -2.
−2x/-2=y-5/-2
