One world trade center (1WTC) is the centerpiece of the rebuilding of the World Trade Center in New York City. The tower is 1776ft tall (including its spire). The angle of the elevation from the base of an office building to the tip od the pire is 34º. The angle of elevation from the helipad on the roof of the office building to the tip of the spire is 20º.  ~ How far away is the office building from One World Trade Center? Assume the side of the tower is vertical. Round to the nearest foot. ~ How tall is the office building? Round to the nearest foot.

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

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
