If the angles A, B and C forms a triangle, then angle A is 111 degrees.
The sum of the interior angles of a 15-gon is (15-2)x180 degree which is 13x180 degrees or 2340 degrees.
Since you are asked to find the complement you need to find 90 degrees total. An angle of 27 degrees complements an angle of 63 degrees. Your answer is 27 degrees.
Angle in triangle abc measure 27, 73 and 80, what kind of triangle is abc
Yes.
Assuming you meant ratio is 2:3:5 then: A: Since the angles have this ratio, we can express their measures as 2x, 3x, and 5x for some value x. Since the angles are complimentary, their sum must be 90 degrees (pi/2 radians). This means that: 2x+3x+5x = 90 (pi/2) 10x = 90 (pi/2) x = 9 (pi/20) So the angles have measure: 18, 27, 45 degrees or pi/10, 3pi/20, and pi/4 radians
180 - (27 + 58)...
An acute angle
27 degrees
The complement of a 27-degree angle is the angle that, when added to the original angle, equals 90 degrees. Therefore, the complement of a 27-degree angle would be 63 degrees.
Complementary angles total 90°. The complementary angle of 27° is 90 -27 = 63°.
90 - 27...
It is: 90-27 = 63 degrees
27 degrees
180-27 = 153 degrees
It is: 90 -27 = 63 degrees
obtuse The complement is 180°-153° = 27°
An angle of 27 degrees is an acute angle
