Problem A builder makes staircases where each step is 28 cm 28cm28, start text, c, m, end text long and rises 18 cm 18cm18, start text, c, m, end text so people don't trip. Every staircase has a stringer — a diagonal support connecting all of the steps. 28 cm 28cm 18 cm 18cm stringer stringer A certain staircase will have 6 66 steps. ℓ ℓ What is the length ℓ ℓell of the stringer for this staircase? Round your answer to the nearest tenth of a centimeter.

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.

step-by-step explanation:

hope this !

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
