a²=b²+c²-2bc*cos A
==>a²=13²+6²-2*13*6*cos 50°=104.7251...
==>a=10.2335...

sin C/c=sin A/a
==>sin C=qin 50°-6/10.2335...=0.449137...
==>angle C=26.688394...°

angle B==180°-50°-26.688394...°=103.311610...°

A race car travels at a speed of 230 miles per hour. The race track on which the car is competing is 400 miles long. About how l
olga nikolaevna [1]
To solve for this we will be using the formula S = D/T

S = Speed
D = Distance 
T = Time

First we need to re-arrange this formula to solve for time

T= D/S

T = 400/230

T=1.74 hours

.74 hours is close enough to .75 that we can say it is 45 minutes

So it is 1 hour and 45 minutes
