Answer 1

r = 290°

Explanation:

Exterior angle property:

In a triangle, exterior angles equals the sum of interior opposite angle.

In triangle A,

x + 90 = 125 {Exterior angle property}

x = 125 - 90

x = 35°

In triangle B,

y + 90 = 125

y = 125 - 90

y = 35°

x + y + r = 360 {Complete angle}

35 + 35 + r = 360

70 +r = 360

r = 360 - 70

r = 290°
