Question

find angle BCD. plzzzzzzzzzzzzzzz z,,,zz,,zz ​

Answer 1

Answer:

102+30= bcd

BCD=132 by exterior angle theorem that indicates that the exterior angle is the sum of opposite angles that is in linear pair with exterior Angle

Answer 2

Explanation:

angleBAC+angleACB+angleCBA =180(sum of all angles of a triangle)

100+30+angle ACB=180

angle ACB=50

angle ACB+angle BCD=180(angles in linear pair)

50 +angleBCD=180

angle BCD = 130
