Question

one of the angles of a triangle measures 100°and other two angles are equal .find the measures of each of the equal angles.​

Answer 1

Answer:

40° and 40°

Step-by-step explanation:

Let the other equal angles be x.

Sum of all angles in triangle = 180°

=> 100° + x + x = 180°

=> 2x = 80°

=> x = 40°

Answer 2

Answer:

the measure of all three angles of traingle is 180°

so, other two sides = 2x

2x + 100 = 180°

2x = 180°-100°

2x = 80°

x = 80° ÷ 2

x =40°
