As per the problem
The escalator make a 30° angle with the floor .
The escalator have a vertical height of 36 feet.
Now draw the diagram with the given information, the diagram is attached below
From the diagram,
Horizontal length=AB=d
Distance traveled by the person on the escalator stairs=AC=l
In triangle ABC,
Again in triangle ABC, Using Pythagoras Theorem
The horizontal length needed is
The distance a person would travel on the escalator stairs is 72 ft
Hello!
To find a length, we want to find how many radians our arc length is. Let's convert our 73 degree angle into radians, which will give us our radian length.
(73)≈1.2741
Now, we know our arc length is equal to about 1.2741 radians. Let's multiply this by our radius.
1.2741(6.48)≈8.3
Therefore, our arc length is about 8.3 inches.
I hope this helps!
There is 180 degrees on a straight line so you can work out the unnamed angle in the triangle by doing 180-115 which is 65
There are also 180 degrees in a triangle so to work out y you do 180 - (65+85) = 30
So y = 30 degrees
C. ABCD is a trapezoid, but it is not an isosceles trapezoid.
Step-by-step explanation:
ABCD is a trapezoid not an isosceles trapezoid. Because opposite sides of isosceles trapezoid are parallel.
The characteristics of trapezoid are legs, lower base angles, upper base angles diagonals are congruent.
The characteristics of isosceles trapezoid are bases are parallel, opposite sides are same length.
From the above mentioned characteristics of an Trapezoid and Isosceles trapezoid the given is trapezoid.
Given data clearly mentioned in diagram ABCD, where a≠b, a≠0 and b≠0 So, it is trapezoid.
Result:
So, the given is Trapezoid not an isosceles trapezoid . Because ABCD, where a≠b, a≠0 and b≠0.
