Answer 2

Here is the Answer....

__________________-

In Δ PSR,

∠SPR + ∠PSR + ∠PRS = 180°

100°  + 35° + ∠PRS = 180°

∠PRS = 180 - 135

• ∠PRS = 45°

_______________________

Since PQ || SR,

∠QPR = ∠PRS     (alternate angles)

• ∠QPR = 45°

_______________________

Now, In ΔPQR

∠PQR + ∠QPR + ∠PRQ = 180°

110° + 45° + ∠PRQ = 180°

∠PRQ = 180 - 155

• ∠PRQ = 25°
