Answer:
Step-by-step explanation:
She is riding fastest when the slope is steepest, in this case from 2 to 3 hours.
First, find the value of <em>x</em>. Then, use the measures of the arcs to find the value of <em>w</em>.
When two chords intersect, the measure of the internal angle is equal to the average of the arcs that it encloses:
Since the angle of 70° encloses arcs of 60° and x°, then:
Solve for <em>x:</em>
The sum of the measures of the arcs of a circle must be equal to 360°. Then:
Substitute <em>x=80</em> and solve for <em>w:</em>
Therefore, the value of w is:
