Answer:

x = 50°

d = 40°

Explanation:

Angle sum property of quadrilateral:

Quadrilaterals are four-sided polygon and the sum of all the interior angles is 360°

Sum of all angles of quadrilateral = 360°

60° + x + 3x + 2x = 360

60 + 6x = 360

Subtract 60 from both sides,

6x = 360 - 60

6x = 300

Divide both sides by 6

x = 300 ÷ 6

x = 50°

b) 120° + 110° + 90° + d= 360°

320 + d = 360

Subtract 320 from both sides,

d = 360 - 320

d = 40°
