90o
Complementary angles total 90o so 90 - 80 = 10; the complementary angle is 10o.
Complementary angles consist of 2 angles that add up to 90 degrees; so the complimentary angle to a 31 degree angle is a 59 degree angle.
'a' and 'b' must both be acute, complementary angles.
Complementary angles are angles that add up to 90 degrees. If the smaller angle is x, the larger is 5x, so 6x = 90. X equals 15, and the larger angle measures 75 degrees.

The sum of two complementary angles is 90 degrees. The three angles of a triangle add up to 180 degrees. Hence, if you subtract the complementary angles from 180, you have the measure of the third angle: 180 - 90 = 90 (this is the third angle) As a rule, if two angles of a triangle are complementary, the third angle is a right angle (90 deg). The three angles together form a right triangle.
complementary angles- 2 angles that add up to 90 degrees
Complementary angles add to 90 degrees so the complementary angle to 70 degrees has a measure of 20 deg.
The two angles, other than the right angle itself, MUST be complementary.
If two angles of a triangle each measure 55 what is the measure of the third angle?
The complementary angles form a right angle with the shared ray.
Two angles of a triangle add up to 65°. What is the measure of the third angle?
Complementary angles total 90o so 90 - 80 = 10; the complementary angle is 10o.
Complementary angles consist of 2 angles that add up to 90 degrees; so the complimentary angle to a 31 degree angle is a 59 degree angle.
the larger angle is 60 and the smaller angle is 30.complimentary angles are 2 angles forming 90 degrees.
It is 15 degrees because complementary angles add up to 90 degrees
It is 15 degrees because complementary angles add up to 90 degrees
