Answer:
Step-by-step explanation:
we know that in a quadrilaterals the opposite angles makes 180°
for example there is a rectangle ABCD . in this if take two angles which are opposite to each other and add the angles of both we would get 180°
i.e., ∠A+∠C= 90°+90°= 180°
now let us take the question.
here it is given ,
two angles 2x°, and 70°, which are opposite to eachother.
as per the rule of quadrilaterals,
2x° + 70° = 180 (opposite angles makes 180°)
⇒ 2x° = 180° - 70°
⇒ 2x° = 110°
⇒ x° =110°÷2
⇒ x° = 55°
∴2x° = 2×55 = 110°
