20 and 60 degrees

Answers

Answer 1
Answer:

Answer:

Other two angles are 80 and 80 degrees

Step-by-step explanation:

In an isosceles triangle , one angle measures 20 degrees.

In an isosceles triangle two angles are equal

In a triangle , we have three angles

one angle is 20 degree. sum of angles in a triangle is 180 degree

other two angles is equal to 180 - 20 = 160

other two angles are of equal degree so we divide by 2

160/2= 80

Other two angles are 80 and 80 degrees
Answer 2
Answer: 80+80=160+20=180

triangles should always equal 180
