Question

of the three angles of a triangle one is three times the smallest and another one is five times the smallest.the measure of the largest angle is?

Answer 1

Answer:

Sum of all angles= 60+30+90=180. This holds true. Hence the smallest angle is 30 degree. Hence we can also say it is a right angled triangle as it has one angle twice the smallest and another thrice the smallest.

Answer 2

Step-by-step explanation:

Let the angles be = x

angle 1st = x

2nd = 3x

3rd = 5x

Sum of triangle = 180°

x + 3x + 5x = 180°

9x = 180°

x = 180/9

angle 1st = 20°

2nd = 3x = 3×20 = 60°

3rd = 5x = 5×20 = 100°
