Hello!

Here we have sin=opp/hyp so the sin of 45deg= 7/b so we have

Sqrt(2)/2 = 7/b so b= 7/sqrt(2)/2= 14/sqrt(2)= 14*sqrt(2)/2= 7*sqrt(2) so the final simplified answer for the value of b= 7*sqrt(2)

Any questions please ask. Thank you kindly.

Suppose you have entered 115-mile biathlon that consists of a run and a bicycle race. During your​ run, your average velocity is
Maksim231197 [3]

Answer:

The distance of the run was 27 miles and the distance of the bicycle race was 88 miles.

Step-by-step explanation:

Since I have entered 115-mile biathlon that consists of a run and a bicycle race, and during my run, my average velocity is 9 miles per hour, and during my bicycle race, my average velocity is 22 miles per hour , and I finish the race in 7 hours, to determine what is the distance of the run and what is the distance of the bicycle race, the following calculations must be performed:

7 x 22 + 0 x 9 = 154

5 x 22 + 2 x 9 = 128

4 x 22 + 3 x 9 = 115

Therefore, the distance of the run was 27 miles and the distance of the bicycle race was 88 miles.
