Question

An exterior angle of a triangle measures 160°. If the interior opposite angles are
in the ratio 3 : 1, find the measure of all the angles of the triangle.

Answer 1

Answer:

120,40,20

Step-by-step explanation:

3:1=3x,1x

3x+1x=160

4x=160

x=160/4

x= 40, 3x =3×40= 120,1x=1×40= 40

the remaing is y

then 120+40+ y = 180

y= 180- 160

y = 20
