ANSWER


{ \tan(y) } = ( √(7) )/(3)

Step-by-step explanation

If


\sin(X )= (3)/(4)


\sin(X )= (opposite)/(hypotenuse)

This implies that the opposite is 3 units and the hypotenuse is 4 units.

We now find the adjacent side using the Pythagoras Theorem.


{a}^(2) + {o}^(2) = {h}^(2)


{a}^(2) + {3}^(2) = {4}^(2)


{a}^(2) + 9 =16


{a}^(2) =16 - 9


{a}^(2) = 7


{a}= √(7)


{ \tan(y) } = (opposite)/(adjacent)

The side opposite to Y is √7 and the side adjacent to Y is 3.


{ \tan(y) } = ( √(7) )/(3)

In triangle XYZ, angle Z is a right angle. If sinX = 3/4, find tan Y.-example-1
