Question

In a triangle the three angles are x°, 2x° and 3x°

a) Show that 6x = 180 _______________________________________
____________________________________________________________
b) Find the value of x
x = _____°

Answer 1

x = 30 degrees because

all angles of a triangle = 180

6x = 180 divide by 6

x = 30

To make sure it’s right plug it in

x, 2x, 3x

30 + 2(30) +3(30) = 180

so x = 30
