Question

in a ∆bc , if Ab= 3cm ,Ac = 3cm and angel A =50 then find angel B​

Answer 1

65°

Step-by-step explanation:

it is an isosceles ∆

so

< b = < c

<a+<b+<c= 180

50 + 2<b = 180

2<b=180-50

=130

<b = 130/2

= 65°

Answer 2

Answer:

∠b = 65°

Step-by-step explanation:

ab = ac = 3 cm

so, ∠c = ∠b

∠a +∠b +∠c = 180°

2∠b = 180° - 50°

∠b = 65°
