Question

One of the angles of a triangle is 80° and the other two angles are equal. Find the

measure of each of the equal angles.
​

Answer 1

Answer:

50

Step-by-step explanation:

80 + x + x =180

80+2x =180

2x=180 - 80

2x = 100

x = 100/2

x = 50

Answer 2

Answer:

Let the two equal angles be x

So, x + x + 80 = 180 ( Angle sum property of triangle )

2x = 100 => x = 100/2 = 50

So, the equal angles are 50° and 50°
