Two complementary angles add up to 90 degrees. Here we can say that one angle is the complement of other or the one angle is the complementary to the other angle. Math. So the supplement of a 65 degree angle is 115 because together they make 180 degrees. (y – 20)° and (y + 30)° are the measures of complementary angles. vii. Since they are complementary angles, the angle + the angle's complement = 90 degrees So if you have an angle that is 20 degrees, then the complement angle measures 70 degrees. 54, 36 c. 68, 112 d. 112, 68 . a. An acute angle is an angle whose measure is more than 0 degrees but less than 90 degrees. The Questions and Answers of An angle is twice its complementary angle. Determine its measure ... Let the angle be x. Select the measure of the complement or supplement of the angle. Find the measure of the angle and its complement. 6x=450. So 30 degrees is complementary to 60 because they together make 90. 38, 52 b. Can you explain this answer? Complementary Angles: It is defined as, any two angle that add up to 90 degrees( a right angle). Supplementary angles form a straight line and have a sum of 180 degrees. We know that two lines having a common vertex form an angle. Hope this helps you understand, it isn't pointless trust me. x=5(90-x) x=450-5x. Let the measure of the complementary angle be a°. We have studied basic geometrical terms. A/q. ∴ x + a = 90 ∴ x + a – x = 90 – x …. Answer: (d) Explanation : Definition of complementary angles. A complement of an acute angle must be an acute angle. kashveesingh kashveesingh 20.08.2017 Math Primary School The difference in the measures of two complementary angles is 12 degree. is done on EduRev Study Group by Railways Students. Here we say that the two angles complement each other. (Subtracting x from both sides) ∴ a = (90 – x) ∴ The measure of the complement of an angle of measure x° is (90 – x)°. This discussion on An angle is twice its complementary angle. What is the measure of the angle?a)30°b)90°c)60°d)120°Correct answer is option 'C'. An angle that measures 90 0 is a complementary angle and whose measure is 180 0 is a supplementary angle. For example, even if the angle was the minimum 1 degree, the complement is still 89 degrees, which is still acute. The measure of the complement of any angle A is ninety degrees minus the measure of angle A. Two supplementary angles add up to 180 degrees. The missing angle measures 103 degrees. When the sum of two angles is 90°, then the angles are known as complementary angles. Complementary and supplementary angles are the two types of angles based on their measures. Then x -30 = the measure of the angle's complement. Complementary Angles. Find the measures of the angles Get the answers you need, now! Question 2. In case you need to set up an equation in addition to finding the answer: Let x = the angle. They always adds up to give positive measures and each angle can only be acute angle measuring less than 90 degree. The measure of the complement of the angle 30° is The sum of the measures of two complementary angles is (a) 180° (b) 60° (c) 45° (d) 90° Answer/Explanation. If the relationship is given, you can subtract the given angle from the sum to determine the measure of the missing angle. In other words, if two angles add up to form a right angle, then these angles are referred to as complementary angles. Determine its measure adarshmishra40 adarshmishra40 27.11.2018 Math Secondary School An angle is equal to five times its complement . x+5x=450. The measure of an angle's complement is 24 less than twice the measure of the angle. Then it's complement will b(90-x). Therefore, any combination of a complement of an acute angle MUST be acute. Now let's parse your question, starting by defining our variables: Let C = the measure of the complement angle and let A = the measure of the original angle. 3. x=450/6=75. Let's Review Complementary angles form a right angle (L shape) and have a sum of 90 degrees. Find an answer to your question an angle is equal to five times its complement .
