Question

one of the angles of a triangle is 80°and the orther two angles are equal. find the measure of each of the equal angles​

Answer 1

Answer:

50 degree

Step-by-step explanation:

one angle =80 degree

total angle of a rectangle =180 degree

180-80 =100 degree

half of 100=50

so the answer is 50 degree

Answer 2

Answer:

50° each

Let x be the two equal angles

80°+x+x=180°

80°+2x=180°

2x=180°-80°

2x=100°

x=100/2

x=50°
