What is the measure of the third angle in triangle ABC? The measure of the third angle is ___°.

The measure of the third angle is 45°

Step-by-step explanation:

Add 75+60=135

Then 180-135=45

8 2/3 is the answer

step-by-step explanation: just use a calculator

- "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."
