For triangle TUV let angle V = 90°.
If angle U = 47° and TU = 13.28, what is the measure of TV​

TV = 9.71

Step-by-step explanation:

sin 47° = TV/13.28

0.7314 = TV/13.28

TV = 9.71

Step-by-step explanation:

Total time is 110 min, the equation:

Tennis takes 40 min longer than swimming, the equation:

Substitute x and solve for y:

Swimming takes 35 min

Let x = 70, then we get:

For the first equation we get y = 40 min

For the second equation we get y = 30 min

No solution, therefore it is not possible
