Answer:

z=44

Step-by-step explanation:

One way to go about this with the given angles is to use the alternate interior angles theorem to find the full measure of ∠C and ∠A. Then, use the same theorem to set ∠BDA as 52°. Subtract all the angle measures from 360 (because the sum of the interior angles of a quadrilateral is = 360 degrees). Then divide the result by 2.

360-84-84-52-52=88

=88/2

=44

So z=44°

Answer:

19.

Step-by-step explanation:

First arrange in ascending order:

16, 16, 18, 19, 21, 25, 27, 30, 34, 49, 50, 58, 59, 71, 75.

There are a total of 15 numbers, so the median is the 8th number = 30.

The lower quartile is halfway alone the first 7 numbers which is the 4th number and it is 19.

The median which is the middle number

In the diagram below, the angle of depression from the top of the lighthouse to a speed boat is 27 degrees. The base of the lig

Answer:

412

feet

Step-by-step explanation:

The angle of depression is always measured from the horizontal.

A triangle is formed by the lighthouse, the ground and the boat. The angle of depression is not in the triangle, but it is equal to the angle of elevation at the boat. (Alternate angles on parallel lines)

The angle at the top of the lighthouse, inside the triangle is:

90°−27°

=63°

The distance to the boat is the side opposite the angle of

63°

while the height of the lighthouse is the adjacent side.

opposite

adjacent

=tan 63°

distance

210=tan 63°

distance=210×tan 63°=412 feet
