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
<h3>Circle Geometry </h3>
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 <u>cyclic quadrilateral</u> 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
