An angle measures 42 degrees more than twice the measure of its complement. what is the measure of its complement? a. 16º b. 26º c. 46º d. 106º -!

First, lets comprehend the question.

A complement of a number is a number in which added to the number, it will be measure 90.
The phrase: "More than" means you gotta add it
The phrase: "twice the complement of the number" means you gotta multiply the complement by 2.

Next step, solving.
To get the complement of 42° we must subtract it by 90°.
So 90-42=48. So the complement of 42 is 48 since they both add up to 90.
Now it says here to multiply the complement twice. So multiply 48 by 2

X^2 - 4x +(4/2^2) + y^2 + 8y + (8/2^2) = -4 + (4/2^2) + (8/2^2)(x + 2)^2 + (y + 4)^2 = -4 + 4 + 16your center is (-2, -4) and the radius is the sqrt of -4 + 4 + 16 which is 4
