Question

in a triangle, if the second angle is 2 times the first angle and the third angle is 3 times the first angle,find the angles of the triangle.

Answer 1

a + b + c = 180

b = 2a

c = 3a

a + 2a + 3a = 180

6a = 180

a = 30

b = 2(30)

b = 60

c = 3(30)

c = 90

Answer:

a = 30

b = 60

c = 90
