Yes, the other angle would be 40o to make a total of 60o + 80o + 40o = 180o.

There are 180 degrees in a triangle 180 -80 -60 = 40 degrees Answer: 40 degrees
40 degrees
Using Pythagoras' theorem the hypotenuse of the right angle triangle is 100 cm
It could be an isosceles triangle with angles of 20, 80 and 80 degrees
Let's say that the angles of this triangle is supplementary. So our equation will be: 80 + 60 + x = 180 Solve for x (80 + 60) 140 + x = 180 x = 180 - 140 x = 40 That is the measurement of the third angle. To check, just simply add the 3 and you'll get 180 - ericka janolo http://www.friednster.com/ekang03
