Answer 1

Answer:

hey!!

Step-by-step explanation:

according to the question,

angle a = 50 d.g

angle b = 80 d.g

hence , using angle sum property,

angle a + angle b+angle c= 180 d.g

80 + 50 + angle c = 180

angle c = 50 d.g

since opposite angles of the triangle is equal , i.e angle a=angle c

Δabc is isoceles

we know that in an isoceles Δ , opposite angles and sides are equal

∴ ab = bc

⇒ bc = 4cm
