down left and down right

Answer 2

Answer:

x=50°, y=80°

Step-by-step explanation:

Take the point as T which have 90° in it.

To find x:

In triangle QTR

Angle TQR+ angle QRT+ angle QTR= 180°{Sum of angles in a triangle add up to 180°}

40°+ QRT+ 90°=180°

x=180°-(90°+40°)

x=180°-130°

x=50°

In triangle PQR

Angle PQR+ angle PRQ+ angle QPR=180°{Reason stated above}

QPS+30°+50°+40°=180°

QPS=180°-(50°+30°+40°)

QPS=180°-120°

QPS=60°

Now to find y:

In triangle PSQ

Angle PQS+angle QPS+angle PSQ=180°{same reason}

40°+60°+y=180°

y=180°-(60°+40°)

y=180°-100°

y=80°
