One of the angles of a triangle is 100° and the other two angles are equal. Find each of the
equal angles.​

Answer 1

Please mark me as a brainllist answer

Step-by-step explanation:

Angle of triangle=180°

one angle = 100°

so each two angles = 180°– 100°

= 80°÷2= 40°

Answer is 40°

Answer 2

Answer:

by angle sum property

we know that sum of all the sides is 180

let the unknown equal angles be x

now,

100°+x+x = 180°

100°+2x = 180°

2x = 180°-100°

2x = 40°

x = 40/2

x = 20
