The 3rd angle has to be 110 degrees therefore it is an obtuse triangle
No, the angles 40 degrees, 60 degrees, and 80 degrees do not make a triangle because the sum of the interior angles of a triangle must be 180 degrees. In this case, the sum of the angles 40 degrees, 60 degrees, and 80 degrees is 180 degrees, which means they lie on a straight line and do not form a closed 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.
An acute angled scalene triangle.

The 3rd angle has to be 110 degrees therefore it is 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.
180 degrees - 100 degrees - 40 degrees = 40 degrees
Scalene
It is either a triangle on a curved surface or a polygon with 4 or more sides.
There are 180 degrees in a triangle 180 -80 -60 = 40 degrees Answer: 40 degrees
No, the angles 40 degrees, 60 degrees, and 80 degrees do not make a triangle because the sum of the interior angles of a triangle must be 180 degrees. In this case, the sum of the angles 40 degrees, 60 degrees, and 80 degrees is 180 degrees, which means they lie on a straight line and do not form a closed triangle.
Yes an isosceles triangle can have two equal acute base angles of 40 degrees and an apex angle of 100 degrees
30
There is no river at 30 degrees north and 40 degrees east.
A triangle on a concave surface.
