The course for a local triathlon has the shape of a right triangle. The legs of the triangle consist of a 4-mile swim and a 11 mile run. The hypotunuse of the triangle is the biking portion of the event. How far is the biking part of the triathlon?

The biking part of the triathlon is 11.70 miles away.

Step-by-step explanation:

From the right angle Δ ABC

Since AB = 4 mile

& BC = 11 miles

⇒

⇒ = 121 + 16

⇒ = 137

⇒ AC =

⇒ AC = 11.70 miles

Thus the biking part of the triathlon is 11.70 miles away.

answer: 80,000

step-by-step explanation:

the population doubles every day.

10,000*2=20,000 day 4

20,000*2=40,000 day 5

40,000*2=80,000 day 6

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
