The awnser is C because there is a right angle which is 90 degrees then there is also a vertical angle of 118 degrees. There is also a supplementary angle of 70 degrees. When you add these angles you get 278 degrees which you subtract from 360 to find the last angle which is K and you get 82 degrees

Answer:

a person travel 50 ft from the bottom to the top of the escalator

Step-by-step explanation:

An escalator lifts people to the second floor of a building, 25 ft above the first floor. The escalator rises at a 30 degree angle

The escalator forms a right angle triangle

opposite to 30 degree angle is 25 feet. to find the distance from the bottom to the top of the escalator we find the hypotenuse

let x be the hypotenuse

$sin(theta)=\frac{opposite}{hypotenuse}$

$sin(30)=\frac{25}{x}\\x sin(30)= 25\\x=\frac{25}{sin(30)} \\x=50\\$

a person travel 50 ft from the bottom to the top of the escalator
