What type of figure (polygon) are we referring to' you do not say.
Assuming you mean a triangle.
Then the sum of the interior angles of a triangle is 180 degrres.
Hence A + B + C = 180
Substituting
A + 42 + 27 = 180
Subtract '42' & '27' from both sides
A = 180 - 42 -27
A = 138 - 27
A = 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.
A reflex angle is more than 180 degrees but less than 360 degrees. Therefore the reflex angle to 85 degrees is 275 degrees (360 - 85 = 275).
180 - (27 + 58)...
27 degrees
Complement angle of 27 degrees is (90-27) = 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°
Each exterior angle = 360/27 = 13.33... degrees So each interior angle = 180 - 13.33... = 166.66... degrees.
An angle of 27 degrees is an acute angle
