he Statue of Liberty is approximately 305 feet tall. If the angle of elevation of a ship to the top of the statue is 22.9 degree
Andru [333]

Answer:

is at a distance of 722 feet

Step-by-step explanation:

we have the angle that forms between the water and the imaginary line between the ship and the tip of the statue

we have the statue height that would be the opposite leg to our angle and we want to know the distance of the ship to the statue that would be the adjacent leg

we see that it has (angle, adjacent, opposite)

well to start we have to know the relationship between angles, legas and the hypotenuse

a: adjacent

o: opposite

h: hypotenuse

sin α = o/h

cos α= a/h

tan α = o/a

it's the tangent

tan α = o/a

we replace the values ​​and solve

tan α = o/a

tan 22.9 = 305/a

a = 305/tan22.9

a = 305/0.4224

a = 722

is at a distance of 722 feet

Find the degree measure of each angle in the triangle
Karo-lina-s [1.5K]

Answer:

∠L = 43°

∠M = 121°

∠N = 16°

Step-by-step explanation:

<u>Start by setting all sides equal to 180</u>

3x - 5 + 7x + 9 + x = 180

<u>Add like terms</u>

11x + 4 = 180

<u>Solve for x</u>

11x + 4 = 180

      - 4     - 4

      11x = 176

     / 11     /11

        x = 16

<u>Now, plug in 16 for all instances of x on the triangle and solve.</u>

∠L = 43°

∠M = 121°

∠N = 16°
