You are installing a ramp for your house because grandma is coming to live with you! If the measure of angle B is 90 degrees and the measure of angle C is 17 degrees, what is the measure of angle A?

73

Step-by-step explanation:

I Gotchu!

180=90+17+x

90=17+x

73=x

73!

i pretty sure it is

- "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."
