Question

In the given figure, BD=DC and ∠CBD=40°, find ∠BAC​

Answer 1

Step-by-step explanation:

if BD=DC then,

it is an isosceles triangle

angle CBD=angle BCD

or

2CBD----(1)

as we know that the sum of all interior angle is 180 then

angle CBD+ angle BCD +angle BDC = 180

2CBD+angle BDC =180

2×40+angle BDC=180

angle BDC =180-80

angle DBC =100

angle DBC=angle BAC (opposite angle on same cord are equal)

hence angle BAC=100°

have a great day ahead❤❤❤
