Question

In the following figures (not to scale), `overline(PA) and overline(PB) ` are equal chords and ABCD is a cyclic quadrilateral. If `angle DCE=80^@, angle DAP=30^@` then find `angle APB`.
A. `40^@`
B. `80^@`
C. `90^@`
D. `160^@`

Answer 1

Correct Answer - B
Recall the properties of cyclic qudrilateral.
`angle PAB=angle PBA and angle DAB =angle DCE`.
