We are given the value of a and c; a is the width of the ellipse and c is the focus of the ellipse. For an ellipse the equation to be used to find b or the length of the ellipse is:
a^2 = b^2 + c^2
substitute the values in the equation to solve for the missing variable:
8 units is 2a, therefore, a = 4
4^2 = b^2 + 3^2
solve for b:
b = √7 units
Therefore, the value of b is √7 units. To solve for the length of the ellipse (2b), multiply b with 2:
2b = √7 * 2
Length = 2√7 units
Correct answer would be a and F
Answer:
w=-2
Step-by-step explanation:
9(w-4)-7w=5(3w-2)
9w-36-7w=15w-10
9w-7w-15w=-10+36
-13w=26
w=-2

Answer:
42 and 138
Step-by-step explanation:
Supplementary angle mean that the sum of both angle will be 180 degrees. If the angle is X and Y the equation will be:
x + y = 180
x= 180-y
If three times the measure of one angle(X) is 12 degrees less than the measure of the other(Y), the equation will be
3x= y-12
If you insert first equation to second equation, you can find out:
3x= y-12
3(180-y)= y-12
540-3y= y-12
540+12= y+3y
552= 4y
y= 138
x=180- y
x= 180-138
x= 42
