Answer:
sum of angles =180
7x+8x=180
x=180/15
x=12
apc=7x=84
bpc=8x=96
Step-by-step explanation:
Answer:
∠APC = 84°
∠BPC = 96°
∠BPD = 84°
∠DPA = 96°
Step-by-step explanation:
Given that-
∠APC : ∠BPC = 7 : 8
Let ∠APC = 7x
∠BPC = 8x
By figure, ∠APC and ∠BPC are the liner pair of angles on a straight line.
So, ∠APC + ∠BPC = 180 ( According to straight line property )
7x + 8x = 180
15x = 180
x = 12
So, ∠APC = 7x
= 7×12
∠APC = 84°
∠BPC = 8x
= 8×12
∠BPC = 96°
According to the given figure-
∠APC and ∠BPD are opposite angles.
So ∠APC = ∠BPD ( because if two lines intersect at any point then opposite angles are equal)
S0, ∠BPD = ∠APC
∠BPD = 84°
According to the given figure-
∠BPC and ∠DPA are opposite angles.
Then ∠DPA = ∠BPC ( because if two lines intersect at any point then opposite angles are equal)
So, ∠DPA = 96°
