180 degrees - 100 degrees - 40 degrees = 40 degrees
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
A triangle on a concave surface.
isoselles triangleImproved Answer:-The third angle has to be 90 degrees so it is a right angle triangle.
180 degrees - 100 degrees - 40 degrees = 40 degrees
Scalene
An obtuse angled triangle.
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
scalene
A triangle on a concave surface.
Yes because there are 3 interior angles in a triangle that add up to 180 degrees
right triangle
40 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.
The other acute angle in that triangle is 40 degrees.
