Question

3. In a quadrilateral ABCD, A = 150° and B=C=D find B,C,D​

Answer 1

Step-by-step explanation:

as you know that the sum of all the angles in a quadrilateral is 360 degree so 360 - 150 is equals to 210 210 divided by 3 is equals to 70 so b is equal to C is equal to 70

Answer 2

Answer:

30°

Step-by-step explanation:

if <A=150° so,

<A+<B+<C=180°

150°+<B+<C=180°

<B=<C=180°-150°

<B=30°

given that <B=<C=<D=30°
