Question

if ZA= 50° and angle DCP = 20°, then find angle BDC and angle DPC?
​

Answer 1

Answer:

Given, ∠A=60

∘

∠ABC=80

∘

To find ∠DPC & ∠BCQ

Now, ∠ADC=100

∘

[opposite angles of cyclic quadrilateral are supplementary]

∴∠PDC=80

∘

Similarly, ∠PCD=60

∘

∴∠DPC=180

∘

−80

∘

−60

∘

=40

∘

Now, ∠CBQ=100

∘

∠BCQ=60

∘

⇒∠Q=20
