Answer:
60°
Step-by-step explanation:
This questions tests our knowledge on arcs and arc measures.
-Arc measure is the angle that an arc makes with the circle's center.
-The arc measure is proportional to the arc.
#The sum of the 3 arcs is x+2x+3x=6x
Given a circle has 360°, the arc measurement x can be calculated as:
Hence, the arc measurement x is 60°
Answer:
The rate of the slower cyclist is
and that of the faster cyclist is
Step-by-step explanation:
We let x be the rate of the slower cyclist
From the question, the distance between the two towns is 253 and the time taken for the two cyclist to meet is 5 hours
so we can write the equation
We simplify to get the value for x
Hence the rate of the slower cyclist is
and that of the rate faster cyclist is
