Jonathan sets a camera on a tripod to film birds in a nest. the camera is 1.8 m off the ground and 16.4 m away from the tree. the angle of elevation from the camera to the bird’s nest is 29°. how far above the ground is the bird’s nest? round your answer to the nearest tenth of a meter. 7.3 m 9.1 m 10.9 m 14.3 m

step-by-step explanation:

107 units

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
