∵ TR is a line
∴ ∠PQT + ∠PQR = 180°
⇒    110° + ∠PQR = 180°
⇒ ∠PQR = 180° - 110° = 70°    ...(1)
∵ QS is a line
∴ ∠SPR + ∠QPR = 180°
⇒    135° + ∠QPR = 180°
⇒ ∠QPR = 180° - 135° = 45° ...(2)
In ∆PQR,
∠PQR + ∠QPR + ∠PRQ = 180°
| ∵ The sum of all the angles of a triangle is 180°
⇒ 70° + 45° + ∠PRQ = 180°
| Using (1) and (2)
⇒    115° + ∠PRQ = 180°
⇒ ∠PRQ = 180° - 115° = 65°.

Anushka Agarwal 5 years, 2 months ago

Given: x=1 and y=3. So,when we put the values in the following eq., 3x-4y+9=0 , We get? 3(1)-4(3)+9=0 => 3-12+9=0 => (3+9)-12=0 => 12-12=0 => 0=0 Thus, x=1 and y=3 satisfies the equation 3x-4y+9=0 Hope it helps:)
