Question

One angle of an isosceles triangle measures 140°. Which other angles could be in that isosceles triangle? 80° 20° 50° 40° plzzzzzzzzz help me

Answer 1

Answer:

20°

Step-by-step explanation:

If it's an isosceles triangle, the two remaining angles should be equal. (Angles opposite to equal sides are equal)

∴ one remaining angle = (180° - 140°)/2

                                      = 40° / 2

                                      = 20°
