The opposite angles are equal to are supplementary to each other or equal to each other.

<h3>What is a Quadrilateral Inscribed in a Circle?</h3>

In geometry, a quadrilateral inscribed in a circle, also known as a cyclic quadrilateral or chordal quadrilateral, is a quadrilateral with four vertices on the circumference of a circle. In a quadrilateral inscribed circle, the four sides of the quadrilateral are the chords of the circle.

The opposite angles in a cyclic quadrilateral are supplementary. i.e., the sum of the opposite angles is equal to 180˚.

If e, f, g, and h are the inscribed quadrilateral’s internal angles, then

e + f = 180˚ and g + h = 180˚

by theorem the central angle = 2 x inscribed angle.

∠COD = 2∠CBD

∠COD = 2b

∠COD = 2 ∠CAD

∠COD = 2a

now,

∠COD + reflex ∠COD = 360°

2e + 2f = 360°

2(e + f) =360°

e + f = 180°.

From the top of a 150-ft lighthouse, the angle of depression to a ship in the ocean is 22°. How far is the ship from the base of
zepelin [54]

Answer:

the ship is at a distance of 60 feet

Step-by-step explanation:

we have to think of the problem as a right triangle, since

we have 2 legs and 1 hypotenuse, we know the measure of the leg that gives us the height and the angle that that leg touches

the leg we want to calculate is the opposite of the angle we have, since it does not touch

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

a: adjacent

o: opposite

h: hypotenuse

sin α = o/h

cos α= a/h

tan α = o/a

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

is the tangent

tan α = o/a

tan 22 = o/150

tan 22 * 150 = o

60.6ft = o

round to the nearest foot

60ft

the ship is at a distance of 60 feet
