The measures of two angles of a triangle are 75 and 62º. Find the measure of the third angle. 13°
c. 470
b. 43°
d. 137

B 43

Step-by-step explanation:

Well for a triangle it has to be equal to 180 so you would add 75 and 62 to get 137 so you would add each answer to 137 and whichever one equals 180 is the answer therefor stating that the answer is B 43.

- "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."
