Give triangle TRY, find TY. Round your answer to the nearest hundredth.
3241004551 [841]

The length of TY is 2.26.

Solution:

In ΔTRY, θ = 37°, Adjacent side = 3.

To find the length of TY.

Using trigonometry identity,

$\tan\theta=\frac{{opposite}}{{Adjacent}}

$\tan37^\circ=\frac{{TY}}{3}

$3\tan37^\circ=TY

$3\times 0.75355=TY

$TY=2.26065

TY = 2.26

Hence the length of TY is 2.26.
