right triangle and the other angle would be 70 degrees.
Hope I helped :)
A reflex angle.
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.
Reflex.
As 273° is greater than 180° it is a reflex angle.
This type of angle is called a 'revoloution angle'.
Obtuse triangle
It is a right angle triangle and its 3rd angle is 70 degrees.
Any triangle that has an angle measuring 90 degrees is a right triangle.
acute-angled triangle
It is a right angle triangle and the 3rd angle will measure 30 degrees
It is a right angle triangle providing that the 3rd angle is 30 degrees.
A triangle with the third angle that measures 30 degrees.This triangle is not isosceles nor equilateral but has one obtuse angle.
The 3rd angle is 30 degrees which would form an obtuse or scalene triangle.
It is a right angle triangle and the 3rd angle will measure 30 degrees
The third angle measures 85⁰ (20 + 75 + 85 = 180) consequently, the triangle is an acute angled scalene triangle
The 3rd angle is 70 degrees which would form a right angle triangle.
obtuse scalene triangle
