Question

The exterior angles obtained on producing the base of a triangle both ways are 100° and
120°. Find all the angles of a triangle.​

Answer 1

Answer:

triangle= angles 60°+80°+40°=180

Step-by-step explanation:

one side angle 120°= 180-120=60

another side angle 100°=180-100=80

then last angle = 60+80=140

= 180-140=40°

angles = 60+40+80= 180°
