Answer:
angle POR= 75
angle ROQ=105
angle POS=15
angle SOQ=15
Answer:
angles are 75° and 105°
Step-by-step explanation:
Well This a bit long but it's ok
The lines pq and rs intersect at point O
At point O the sum of the angles is 360° (Since one whole point has 360° as sum)
And another info we can derive is that angles ∠POR and ∠SOQ are vertically opposite angles(equal to each other)
Similarly ∠ROQ and ∠POS are also vertically opposite hence Equal to each other
So this all what we know now :--
Sum of 4 angles=360°
∠POR = ∠SOQ
∠ROQ = ∠POS
And
Since ∠POR : ∠ROQ = 5:7
∴ ∠POR : ∠ROQ = ∠SOQ : ∠POS = 5:7
∴ ∠POR + ∠ROQ + ∠SOQ + ∠POS =360°
Let The angles be 5x and 7x = 5:7
⇒ 5x + 7x + 5x + 7x =360°
⇒24x = 360°
⇒ x = 360°/24 = 15°
So x = 15
∠POR = ∠ROQ = 5x = 5*15° = 75°
∠ROQ = ∠POS = 7x = 7*15° = 105°
we can also prove it by
75+75+105+105 =360
Hence proved
