Answer:
x ≈ 55.6
Step-by-step explanation:
Using the sine ratio in the right triangle
sin20° = 
= 
( multiply both sides by x )
x × sin20° = 19 ( divide both sides by sin20° )
x = 
≈ 55.6 ( to the nearest tenth )
6 1/3 + k + 3 5/6 + 5 1/2 = 26 1/6
Add your fractions
6 1/3 + 3 5/6 + 5 1/2 = 15 2/3
now You need to isolate k on one side of the equation by using the subtraction method of equality.
k + 15 2/3 = 26 1/6
k = 10 1/2
Hope this helps
