You can solve by substituting (x) for the unknown angle and (x + 40) for the angle plus 40 degrees and set the equation as: x + (x + 40) = 90 (then simplify) 2x + 40 = 90 (then isolate the known from unknown by subtracting 40 from each side of the equation) 2x = 50 (divide both sides by 2 to solve for x) x (the unknown angle) = 25 degrees now you can substitute the value of the angles to prove the equation.
Complementary angles add to 90 degrees. So complement of 18 deg is 72 deg.
5 degrees angle, because the sum of two complementary angles is 90 degrees.
A pair of angles are complementary if their sum is 90 degrees. Therefore, the complement to a 35 degree angle measures 90 - 35 = 55 degrees. This can be effectively displayed when placing both angles so that they form a right angle.
The definition of complementary is two angles together that form a right angle or 90 degrees. The way to find the complement of an angle is to subtract that angle from 90 degrees. In this case 90 subtracted by 79 equals 11. The complement of a 79 degree angle is an 11 degree angle.
Since the sum of the two complement angles is 90⁰ , then the complement of a 60⁰ angle is a 30⁰ angle.
16.5 degrees
It is 9 degrees because complementary angles add up to 90 degrees
Complementary angles add to 90 degrees. So complement of 18 deg is 72 deg.
5 degrees angle, because the sum of two complementary angles is 90 degrees.
An angle and its complement add to 90 degrees. Hence an angle of 41 degrees has 49 degrees as its complement.
Assuming two angles are complementary, an angle can have the same measure as it's complement when it measures 45 degrees. BECAUSE 45 +45 =90!!
The complement is 60 degrees.
28 degrees. Complementary angles add up to 90 degrees
Complementary angles sum to give 90 degrees. Therefore the complement to an 85 degree angle is a 5 degree angle.
A pair of angles are complementary if their sum is 90 degrees. Therefore, the complement to a 35 degree angle measures 90 - 35 = 55 degrees. This can be effectively displayed when placing both angles so that they form a right angle.
Complementary angles add up to 90 degrees. If one angle is 65 degrees, its complement is 90 - 65 = 25 degrees.
The definition of complementary is two angles together that form a right angle or 90 degrees. The way to find the complement of an angle is to subtract that angle from 90 degrees. In this case 90 subtracted by 79 equals 11. The complement of a 79 degree angle is an 11 degree angle.
