Answer:
x+y+3=0
then
y=−3−x
x-101y-2-3-4
3x−2y+4=0
then
x=32y−4
x-125y-202The point of intersection is (-1, -2)

Answer:
x=37 and y=53
Explanation:
Given
∠SQR = 28°
∠QRT = 65°
To Find
Value of x and y
Solution
∠SRQ +∠QRT = 180° [ Linear Pair ]
➨∠SRQ + 65° = 180°
➨∠SRQ = 180° - 65°
➨∠SRQ = 115°
∠SQR + ∠SRQ + ∠QSR = 180° [Angle Sum Property of triangle ]
➨ 28° + 115° + ∠QSR = 180°
➨ ∠QSR + 143° = 180°
➨ ∠QSR = 180° - 143°
➨ ∠QSR = 37°
∠PSR = ∠QSR + ∠y
➨90° = 37° + ∠y
➨∠y = 90° - 37°
➨∠y = 53°
∠x + ∠y + ∠SPQ = 180° [ Angle Sum Property of triangle ]
➨∠x + 53° + 90° = 180°
➨∠x + 143° = 180°
➨∠x = 180° - 143°
➨∠x = 37°
Therefore, x = 37° and y = 53°
