Question

8) one of the angle of a triangle have measure of 60 degree and other two angles are equal . find these two angles. ​

Answer 1

Answer:

65 and 65

Step-by-step explanation:

let one angle of traingle be 'x' and let the other two angles be 'y' and 'z' so, given that 'y' and 'z' angles are equal .....we know that sum of all the angles in a traingle is 180degrees so that x+y+z=180...such that x+y+y=180(since angles 'y'and'z'are equal angles i.e, y=z) ...now x=60 .. therefore 60+y+y=180 ; 60+2y=180 ; 2y =180-60 ; 2y=130 ; y=65 ; so the other two equal angles are 65 and 65.
