An Obtuse Triangle
Chat with our AI personalities
Well, isn't that a happy little triangle Tyler has there! To find the measure of the third angle, we can use the fact that the sum of all angles in a triangle is always 180 degrees. So, if we add 35 and 85 together, we get 120 degrees. Subtracting that from 180 degrees leaves us with 60 degrees for the measure of the third angle. Happy painting, my friend!
All triangles have angles that total 180degrees. If given 2 angles add them together and subtract (or take away from) 180, answer is angle. Example A triangle has 2 angles of 90 & 30 degrees what is the 3rd angle. 90+30=120, 180-120=60degrees
120 degrees.
It is the equilateral triangle that has the largest exterior angle of 120 degrees
