Question

ABCD is a cyclic quadrilateral and AB is diameter and angle D is 130. find X

Answer 1

Answer:Therefore X=40

Step-by-step explanation:

Draw a line joining A and C.

therefore,∠ACB=90 (angle subtended by the diameter of circle)

and ∠ABC is the supplementary angle of ∠ADC. (opposite angles of cyclic quadrilateral)

∴∠ABC=180−∠ADC=180−130=50

∠BAC=180−(∠ACB+∠ABC)

=180−50−90=40

Answer 2

Answer:

here is your answer :

Step-by-step explanation:

∠ACB=90

∴∠ABC=180−∠ADC=180−130=50

∠BAC=180−(∠ACB+∠ABC)

=180−50−90=40

I think your ques would be to find angle angle bac
