You have a hybrid problem, one that requires a knowledge of algebra and rudimentary geometry. First, you have to know what the complement of an angle is. If the sum of the measures of two angles equals 90 degrees, they are complements. For example, if two angles have measures of 30 degrees and 60 degrees, they are complementary angles. Put another way, you could say that 60 degrees is the complement of 30 degrees, because 90 - 60 = 30. The second thing is far more difficult: you need to figure out a way to set up an algebraic equation from the words given in the question. Not easy. But let's give it a go. We need to be systematic about it. Let x = "the angle" you are looking for. Let 90 - x = the angle's complement. Let 2x = "twice the angle." And let 2x + 30 = "30 more than twice the angle." Can you see how this is developing? I think we have all the mathematical building blocks -- the words of the equation -- to match the English words. Since the complement is 30 more than twice the angle, the equation is 90 - x = 2x + 30 Now, you must use your algebra skills to solve for x. First, add x to both sides of the equation 90 = 3x + 30 Next, subtract 30 from both sides 60 = 3x Now, divide both sides by three 20 = x So, x = 20. Check the answer. Does it make sense? Let's see. If the angle is 20, its complement is 70. Twice the angle is 40. Is 70 thirty more than 40? Yep. Algebra works!

What is the complement of an angle whose measure is 13 degrees?
The complement of an acute angle A is the angle 90° - A. The complement of 13° is 77°.
What is the degree measure of an angle whose measure is double the measure of its complement?
90 degrees
What is the complement of an angle whose measure is 38 degrees?
52 degrees
Fill in the blank The measure of an angle whose sides overlap is degrees?
The measure of an angle whose sides overlap is 0 degrees. It is than not an angle, but rather a line.
An angle whose measure is less than 180 but greater than 90?
An angle whose measure greater than 90 but less than 180 is an obtuse angle.
What is the complement of an angle whose measure is 13 degrees?
The complement of an acute angle A is the angle 90° - A. The complement of 13° is 77°.
What is the complement of an angle whose measure is 47?
43 degrees
What is the degree measure of an angle whose measure is double the measure of its complement?
90 degrees
What is the complement of an angle whose measure is 38 degrees?
52 degrees
What is the complement of an angle whose measure is 25 degrees?
65 degrees
What is the complement of an angle whose measure 85?
Complementary angles sum to give 90 degrees. Therefore the complement to an 85 degree angle is a 5 degree angle.
What is the complement of an angle whose measure is 72.354 degrees?
The complement is (90 - the angle) or: how much you have to add to the angle to make 90 degrees.(90 - 72.354) = 17.646 degrees.
What is the complement of an angle whose measure is 39 degrees?
It is 51 degrees.
When M is supplemental to an angle whose measure is 125 degrees and P is the complement of an angle whose measure is 70 degrees What is M minus P?
55 - 20 = 35
Find the measure of the complement of an angle whose measure is 62?
28 degrees. Complementary angles add up to 90 degrees
If an angle measures over 90 degrees what is its complement?
obtuse angle * * * * * The complement of an angle greater than 90 degrees is not an obtuse angle! It would be a negative angle, whose measure would be 90 minus the angle whose complement you require. This would only make sense if the direction in which the angles were measured were fixed. For example bearings, which are always measured in the clockwise direction.
Find the complement of an angle whose measure is 73 degrees?
90-73 = 17 degrees
