Question

ABCD is a kite. If angle BCD = 30° , then find angle BDC and angle ABC​

Answer 1

Answer:

Step-by-step explanation:

In kite ABCD

DC = BC

Hence we can call triangle DBC an isosceles triangle

According to angle sum property of triangle

Angle BDC + Angle DBC + Angle BCD =180°

(Here, Angle bdc and cdb are equal taken as x)

So,

x+x+30° =180°

2x = 150°

x=75°

Therefore, Angle BDC = 75°

Answer 2

Answer:

BCD+ABC=180

30°+ ABC =180

ABC= 180-30°

ABC=150
