The 3rd angle has to be 110 degrees therefore it is an obtuse triangle
Yes because there are 3 interior angles in a triangle that add up to 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 acute angled scalene triangle.
50 degrees
The 3rd angle has to be 110 degrees therefore it is an obtuse triangle
scalene
A right triangle, whose the length measure of the side opposite to the angle of 30 degrees is one half of the length measure of the hypotenuse.
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
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.
Yes because there are 3 interior angles in a triangle that add up to 180 degrees
