Question

i dont understand the question someone pls send me the soultion in a few minutes

Answer 1

(i) 4x - 5 = 3x + 15 (∠CPB = ∠APD; opposite angles)

4x - 3x = 15 + 5  

x = 20

(ii) ∠APD = 3x + 15  

= (3 x 20) + 15

= 60 + 15 = 75°

(iii) BPD = 180 - ∠BPC

= 180 - (4x - 5)

= 180 - 4x + 5

= 185 - (4 x 20)

=185 - 80= 105°

(iv) BPC = 4x - 5

= (4 x 20) - 5

= 80 - 5

= 75°
