In triangle JKL, tan(b°) = 3/4 and cos(b°) = 4/5. If triangle JKL is dilated by a scale factor of 1/2, what is sin(b°)? triangle KLJ in which angle K is a right angle and angle L measures b degrees sin(b°) = 3/5
sin(b°) = 4/5
sin(b°) = 5/3
sin(b°) = 5/4

Option (1). Sin(b°) =

Step-by-step explanation:

In a triangle JKL, tan(b°) = and cos (b°) =

If ΔJKL is dilated by a scale factor of , angles will remain unchanged.

Triangle formed after dilation will be similar to triangle JKL.

Since, tan(b°) =

Therefore,

Sin(b°) =

Sin(b°) =

Option (1). Sin(b°) = will be the answer.        

The first answer is correct
