He length of the hypotenuse, line segment gh, in triangle gjh measures 6 cm. line segment jh measures 2 cm.

which is the approximate measure of angle jgh?

18.4°
19.5°
70.5°
71.6°

Using the law of sines, SinA/a = SinB/b = SinC/c

guessing the triangle has a 90 degree angle J for the hyp. of 6 and another leg of 2, we set up the problem like this...

Sin90/6 = SinX/2   (multiply by 2)
2 [ Sin90/6 ] = Sinx
.333333333 = Sinx   (to change to degrees, use the Sin^-1 (.3333333333)
to get the approximate degrees of 19.47 degrees or 19.5 degrees.
