The angles could work out as: 1st angle = 90 degrees, 2nd angle = 30 degrees and 3rd angle = 60 degrees because the 3 angles add up to 180 degrees
The third angle is (128 degrees) minus (the second angle).
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
It is a right angle triangle providing that the 3rd angle is 30 degrees.
It is 90-28 = 62 degrees
Let the second angle of the triangle be A. Then angle 1 = 2A : and angle 3 = 3A - 12 The internal angles of a triangle total 180° therefore :- 2A + A + (3A - 12) = 180 6A - 12 = 180 : 6A = 192 : A = 32 The angles measure 64° , 32° and 84° .
54 degrees
Any triangle with a 90 degree angle is classified as a right triangle.
The third angle is (128 degrees) minus (the second angle).
It is a right angle triangle and the 3rd angle will measure 30 degrees
Obtuse triangle
A triangle with the third angle that measures 30 degrees.This triangle is not isosceles nor equilateral but has one obtuse angle.
Any triangle that has an angle measuring 90 degrees is a right triangle.
right triangle
It is a right angle triangle and its 3rd angle is 70 degrees.
acute-angled triangle
It is a right angle triangle and the 3rd angle will measure 30 degrees
