Question

if m ∠ anc is 80 then it is a abc=?two ∆s are of sane height what is the ratso of their arean it bone are b1& b2​

Answer 1

Answer:

BC=AB

⇒∠A=∠C (As angles opposite to equal side are equal)

let thte angles be x each.

Now by angle sum property

∠A+∠B+∠C=180

∘

⇒x+80

∘

+x=180

∘

⇒2x=180

∘

−80

∘

⇒2x=100

∘

⇒x=50

∘

∴∠A=50
