plz answer this question ​

Answer 1

Answer:

Option d....................

Step-by-step explanation:

R = 180 - 85 (they are in straight line)

R = 95.

Q = 180 -55 (they form straight line)

Q = 125.

S = 90.

Sum of all interior angles in a quadrilateral is 360 degrees.

So,

P + Q + R + S = 360

y + 125 + 95 + 90 = 360.

y + 310 = 360

y = 50.

So, the answer is option (d).

Answer 2

AnglePQR = 180°-55° = 125°(Sum of straight line)

AngleQRS = 180°-85° = 95°(Sum of straight line)

AngleRSP = 90° (Right angled)

Lwt, angleSPQ be y

Since, total sum of the quadrilateral= 360° Therefore, anglePQR + angleQRS + angleRSP + angleSPQ = 360°

= 125°+95°+90°+y = 360°

= 310+y = 360°

= y = 360°-310°

= y = 50°

So, Answer is (D)
