Each of the 3 angles measures 60 degrees. There are 180 degrees in a triangle.
The sum of the angles of a triangle is 180 degrees. So we have: 80 + 60 = 140 degrees, the sum of the two angles of the triangle 180 - 140 = 40 degrees, the measure of the third angle. Thus the measure of the third angle is 40 degrees.
If it is an isosceles triangle then the base angles must be equal angles of 69 degrees because there are 180 degrees in a triangle and 42+69+69 = 180 degrees
Since the sum of the internal angles of a plane triangle is 180 degrees, the measure of the missing angle is 65 degrees. 180 - 74 - 41 = 65 degrees.
Triangles measure 180 degrees. A triangle that has one 90 degree angle is known as a right triangle.
Each of the 3 angles measures 60 degrees. There are 180 degrees in a triangle.
A right triangle.
The total number of degrees in a triangle is 180. this will not change no matter what type of triangle it is. (obtuse, acute, right angle, etc)
130 degrees is the measure of the base angles of an isosceles triangle whose vertex has a measure of 50 degrees.
The angles in a triangle will always equal 180 degrees. 180 - 48.3 - 33.6 = 98.1
It is an obtuse scalene triangle.
The sum of the angles of any triangle is 180 degrees.
The sum of the angles of a triangle is 180 degrees. So we have: 80 + 60 = 140 degrees, the sum of the two angles of the triangle 180 - 140 = 40 degrees, the measure of the third angle. Thus the measure of the third angle is 40 degrees.
An obtuse triangle
A triangle with angles that measure 30, 60, and 90 degrees is a special type of right triangle known as a 30-60-90 triangle. In this triangle, the side opposite the 30-degree angle is half the length of the hypotenuse, and the side opposite the 60-degree angle is √3 times the length of the side opposite the 30-degree angle. This relationship is based on the properties of trigonometry and the ratios of the sides in a 30-60-90 triangle.
A right triangle.
A triangle can't measure 75 degrees. A measure in degrees applies to angles, not to polygons such as triangles. In a triangle on a flat surface, the sum of angles is 180°.
