Answer
When you subtract a negative number, it is the same as addition.
Therefore if you subtract a negative number from a positive number, the result will be positive.
9-(-2)=11

What's the question- what is x?
So for this triangle, since it's not right (No 90° angle, at least not shown), we must use special trigonometric triangles. You may have used Pythagorean Theorem, but you can't unless it's a right triangle.
Now we decide between Law of Sines vs. Law of Cosines. L. of Sines is for when we have 2 angles and one or more sides. L. of Cosines is for when we don't have that 2nd angle, but do have 2 sides... our case here.
Here's how the Law of Cosines works:
where c is the side needed, a & b are the 2 known sides, and gamma (γ) is the angle opposite the side c.
So a = 21, b = 42, γ = 39°
NOPE YOU DID IT CORRECTLY!!
You're "x" = 28.88°
30 students in a class ; 16 are boys
Girls to boys : to find the amount of girls, simply subtract the student total with the boy total.
30 - 16 = 14
Therefore there are 14 girls in the class
So, our ratio should be ~ 14 : 16
Girls to all students :
Girls is 14 students is 30
Therefore the ratio to girls to all students is ~ 14 : 30
Boys to girls : Simply get the boys amount to the other side of the girls amount
Therefore the ratio of boys to girls is ~ 16 : 14
Boys to all students : Get the amount of boys and the amount of all students to the opposite side of each other.
Therefore the ratio of boys to all students is ~ 16 : 30

Having drawn one king, there are 3 kings remaining and a total of 51 cards. Therefore the probability of drawing another king is 3/51 = 1/17.
