Answer:
24.12
Explanation:
Looking from the angle of 56 degrees, you see that the side with 20 degrees is opposite, and x is the hypotenuse.
The trig function that uses both opposite and hypotenuse is sin.
Therefore in order to solve this, you must first set up a trig function:
sin(56)=20/X
In order to solve the equation above you need to multiply sin(56) by x and divide 20 by sin(56).
This gives you the answer of 24.12
