Answer 2

Answer:

80

Step-by-step explanation:

Angle s = 180 - 130 (straight line angle is 180°)

angle s = 50°

similarly angle p and q will be

angle p = 180 - 70 = 110°

angle q = 180 - 80 = 100°

therefore,

sum of interior angle is 360

so,

angle s + angle p + angle q + angle r = 360°

50° + 110° + 100° + angle r = 360°

260° + angle r = 360°

angle r = 360 - 260 = 100°

So,

x = 180 - 100 = 80°
