Question

Will mark brainliest please help

Answer 1

Option A

Opposite angles in a cyclic quadrilateral add up to 180°

So

her

x and 133 are opposite angles

• x+133=180
• x=180-133
• x=47°

Part A is done after part B

Answer 2

Answer:

Quadrilateral: A two-dimensional shape with 4 straight sides and 4 interior angles.

Cyclic Quadrilateral:  A quadrilateral drawn inside a circle where every vertex of the quadrilateral touches the circumference of the circle.

We know that opposite angles in a cyclic quadrilateral are supplementary, which means their sum is 180°

Therefore:

⇒ x + 133° = 180°

⇒ x = 180° - 133°

⇒ x = 47°

Opposite angles in a cyclic quadrilateral add up to 180°
