Step-by-step explanation:
a) We know that sum of interior angles of a quadrilateral is equal to 360°
Therefore,
x + 130 + 61 + 65 = 360
x + 256 = 360
x = 360 – 256
x = 104°
b) Using above property of the quadrilateral
x + 100 + x + 50 = 360
2x + 150 = 360
2x = 360 – 150
2x = 210
x = 210 / 2
x = 105°
Hope the solution is clear to you. :)
