Ratio of the angles of a triangle are 2 : 2 : 5. What is the largest angle?

120 degree 80 degree 110 degree 100 degree

100 degree

Ratio of angles = 2 : 2 : 5 Sum of all angles of a triangle = 180° = 9r                                                        1r = 20° Largest angle = 20° x 5 = 100 degree
