Question

The vertical angle is an isosceles traingle is 80degree. Find measurment of its base angles.​​

Answer 1

Answer:

2x+80=180

2x=180-80=100

2x=100

x=100/2

x=50

Answer 2

Step-by-step explanation:

Let in ΔABC , LA = 80

And the angle is isosceles

hence AB = AC

and the angle opposite the

the side will also be the same So

Now in any triangle sum of angle = 180

LB=∠C

LB=∠C

Let ∠B=∠C=2H∘∠B=∠C=2H∘

∴∠A+∠B+∠C=180∘θ0+21+21=18024=180−80=100x=1002⇒[21=50∘]

∴∠A+∠B+∠C=180∘θ0+21+21=18024=180−80=100x=1002⇒[21=50∘]

Hence base angles are of 50∘50∘ each
