Angle lies in quadrant 4. Without using a calculator, determine which ratio is valid. 1) sin =0.789
2) tan =0.573
3) sin =-1.083
4)tan = 0.841

It must be three because both sine and tangent are negative in Quadrant IV and thus is the only viable answer; however none are correct because the sine function never exceeds -1 or 1, so I believe this is a mistake.

The pie is multyplued by the second step

If there are four friends then each would get, 1.25 or 1 1/4. so this is how i solved 5 ÷ 4 = 1.25 . hope this ; )
