Answer:
see explanation
Explanation:
Assuming you require the value of x
Note the sum of the angles round a point = 360°
Sum the given angles and equate to 360
85 + x + 35 + 2x = 360, that is
120 + 3x = 360 ( subtract 120 from both sides )
3x = 240 ( divide both sides by 3 )
x = 80
Thus ∠x = 80° and ∠2x = 2 × 80 = 160°
