How long is a string reaching from the top of a 13-ft pole to a point on the ground that is 7 ft from the base of the pole?

Formula: a² + b² = c²

Plug in the numbers: (13)² + (7)² = c²

Simplify: 169 + 49 = c²

Simplify: 218 = c^2

note the equal sign. What you do to one side, you do to the other. Root both sides: 218 = c^2

√218 = √c²

c =√218

c = 14.76 ft

14.76 ft is your answer

hope this helps

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
