What is the measure of YW?

We know that and are equal, and we're looking for their sum. First, we'll need to find the value of .

Set the expressions equal to each other:

Subtract from both sides:

Divide everything by :

Now that we have the value of , we can substitute it into the sum of the two expressions to get our final answer.

Substitute:

Simplify:

1. 3

2. 4

3. 1

hope this ! have a great day.

- "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."
