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.
It is a right angle triangle and the 3rd angle will measure 30 degrees
The 3rd angle is 30 degrees which would form an obtuse or scalene triangle.
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
