Question

The ratio of the measures of the three angles of a triangle is 2:2:5 . Find the measure of each angle

Answer 1

Angle 1:Angle2: angle3: total

40 40 100 180

Explanation:

The sum of the angles of a triangle is 180

Angle 1:Angle2: angle3: total

2 :2 :5 : 2+2+5 = 9

Divide 180 by 9

180/9 = 20

Multiply each by 20

Angle 1:Angle2: angle3: total

2*20 :2*20 :5*20 : 9*20

40 40 100 180
