To estimate the height of a building, two students find the angle of elevation from a point (at ground level) down the street from the building to the top of the building is 40°. From a point that is 250 feet closer to the building, the angle of elevation (at ground level) to the top of the building is 57°. If we assume that the street is level, use this information to estimate the height of the building.

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

no solution

step-by-step explanation:

there is not enough information in the problem to solve.

30.5*10=350$

you have to multiply the number without the decimal point then add it later but if its tenn u must move the place value of the decimal point 1 to the right.
