Question

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

Answer 1

Answer:

50

Step-by-step explanation:

hi all

☆we know that the sum of angles of triangle is 180

one angle is 80

let other angle be 'x'

then third angle will also be equal to x. (given)

using angle sum property,

x + x + 80 = 180. (1)

2x=100

x=50. (2)

therefore all angles are 80,50,50

Answer 2

One of the angles of a triangle is given to be 80°

Also, it is given that the other two angles are equal

We have to find the other angles

Let the other two angles be x

Now, we know that the sum of angles in a triangle is 180°

So, 80 + x + x = 180

                   2x = 180 - 80

                   2x = 100

                     x = 100/2

                     x = 50

Hence, the three angles of the triangle will be 80°, 50°, and 50°
