Question

ABCD is a quadrilateral inscribed in a circle, as shown below:

Answer 1

The equation that can be used to solve for angle A is (x+16)° + (6x-4)° = 180°. The correct option is the first option- (x+16) + (6x-4) = 180

Circle Geometry

From the question, we are to determine the equation that could be used to solve for angle A

From one of the circle theorems

Opposite angles of a cyclic quadrilateral are supplementary

That is,

∠A + ∠C = 180°

∴ (x+16)° + (6x-4)° = 180°

Hence, the equation that can be used to solve for angle A is (x+16)° + (6x-4)° = 180°. The correct option is the first option- (x+16) + (6x-4) = 180

Answer 2

Answer:

(x + 16) + (6x − 4) = 180

Step-by-step explanation:

When a quadrilateral is inscribed in a circle, opposite angles are supplementary, meaning they add to 180 degrees.
