Question

in the given figure, what is the value of x​

Answer 1

<R= 70°

<Q= 65°

<P= 180-90 (Sum of adjacent angles is 180°)

= 90°

x+70+65+90= 360 (sum of all the angles of a quadrilateral is 360°)

x+ 225= 360°

x= 360-225

x= 135°

Hope this makes ur day better!!

Answer 2

Answer:

x = 135

Step-by-step explanation:

Given : angle RQP = 65, angle R = 70, angle P = 90

angle SPQ + angle P = 180...........linear pair

angle SPQ + 90 = 180

angle SPQ = 180-90

angle SPQ = 90

angle SPQ + angle RQP + angle R + angle S = 360

90 + 65 + 70 + x = 360

225 + x = 360

x = 360 - 225

x = 135
