The third angle is 81 degrees because 180-41-58 = 81 degrees
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.
It is an isosceles triangle and the 3rd angle is 72 degrees.
The vertex angle of an isosceles triangle is equal to the measure of each of its base angles. Therefore, if one of the base angles measures 42 degrees, then the vertex angle also measures 42 degrees.
The third angle measures 85⁰ (20 + 75 + 85 = 180) consequently, the triangle is an acute angled scalene triangle
180 - 64.6 - 18.7 = 96.7 degrees
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.
Obtuse triangle
It is a right angle triangle and the 3rd angle will measure 30 degrees
acute-angled triangle
It is a right angle triangle providing that the 3rd angle is 30 degrees.
It is an isosceles triangle and the 3rd angle is 72 degrees.
A right angle triangle and the third angle measures 60 degrees
A triangle with the third angle that measures 30 degrees.This triangle is not isosceles nor equilateral but has one obtuse angle.
The vertex angle of an isosceles triangle is equal to the measure of each of its base angles. Therefore, if one of the base angles measures 42 degrees, then the vertex angle also measures 42 degrees.
