Question

Find each of the two equal angles of an isosceles triangle whose third angle is 80 degree​

Answer 1

Answer:

50 degree each

Step-by-step explanation:

a+b+c=180

80 +b+c=180

b+c=100 (opposite angles of isosceles triangle are equal

2b=100

b=50

as b =c

c=50

Answer 2

Answer:

let the other 2 angles be x

x+x+80= 180(sum of angles of triangle is 180)

2x= 180-80

2x= 100

x= 50

The two equal angles are 50⁰ and 50⁰
