Answer:
24.12
Step-by-step 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

Standard equation: (x-h)^2 + (y-k)^2 = r^2
Here, (0-[-6])^2 + (0-[-8])^2 = r^2
Find r: 36 + 64 = 100, so r = 10
Then the desired equation is (x+6)^2 + (y+8)^2 = 10^2
