Sarah used her calculator to find tan(122˚) she wrote down an answer of 0.34. how could sarah recognize that her answer is incorrect

Hello from MrBillDoesMath!

The angle 122 is in the second quadrant where sin is positive and cos is negative. Hence the ratio sin\cos (aka tan) should be a negative number. But 0.34 is positive so something is incorrect.

Thank you,

MrB
