Using the image as a reference, what is the csc of angle 90 - x?

Option (F)

Step-by-step explanation:

Cosec of an angle is the ratio of Hypotenuse and Opposite side.

From the figure attached,

ΔABC is a right triangle.

m∠A + m∠B + m∠C = 180°

m∠A + 90 + x = 180

m∠A = 180° - (90 + x)°

        = (90 - x)°

Now csc (90 - x)° =

                            =

                            =

                            = 1.67

Therefore, Option (F) will be the answer.

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
