5.0 =x
Step-by-step explanation:
Since this is a right triangle
tan theta = opp side/ adjacent side
tan 50 = x / 4.2
4.2 tan 50 = x
5.005365089 =x

here you hope this .
step-by-step explanation:
hypotenuse = √(15² + 8²)
= √(225 +64)
= √(289) = 17
sin(x) = cos(y) = 8/17
they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.
