can someone please please check my work? Will fan and give medal!
sin(tan^-1(4/3))
a. the hypotenuse would be 5
b. Angle theta is the angle whose tangent is 4/3 . Find the sine of angle theta.
for that i have a hard time understanding

a. is correct.
The actual angle value in degress is not necessary.
The sine is 4 over 5.
