Using the info given, solve for the missing value of the right triangle. Round each angle to the nearest degree, each length to the nearest tenth,
& each trigonometric value to four decimal places, if necessary.
Opposite side = 14 in.
Adjacent side = 22 in.
cos O = ?
Choice 'A' O cos = 0.8456
Choice 'B' O Cos 0 = 0.8436
Choice 'C' O cos = 0.8936
Choice 'D' O Cos = 0.0936

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq

answer: 0.64
