Answer:
We know, that the sum of all angles in a quadrilateral is 360° [property of quadrilaterals]
In this figure, ∠A + ∠B + ∠C + ∠D = 360°
Or, 100° + 60° + 70° + x° = 360°
Or, 230° + x° = 360°
Or, x° = 360° - 230°
Or, x = 70° (Ans)
D=x→ 130°
Therefore, the unknown angle `D` in the trapezoid is 130°.

Answer:
D=x→ 130°
Certainly! Let's solve for ‘D’:
Combine the known angles:
Subtract 230° from both sides:
Therefore, the unknown angle `D` in the trapezoid is 130°.
