Answer:

The top left graph

Step-by-step explanation:

Everything should be shaded to the left of x = 2 (because it's less than 2), and there should be a solid line at x = 2 (because it's equal to 2)

Answer:

The first option. On the top left

Step-by-step explanation:

Because it is less than or equal to, it wouldn't be dotted and it would be shaded on the left because everything on that side is less than 2. So, it's the first option. On the top left.

An observer at the top of a tower of height 20m sees a man due East of him at an angle of depression of 27°. He sees another man

kotegsom [21]

Answer:

52.35 m

Step-by-step explanation:

Refer to picture.

Let the distance to men are x and y and the distance between them is d.

The angle of depreciation is 27° and 30°, hence top angle of the triangle is 63° or 60°.

Find the distance from the tower to men:

x = 20 tan 63° = 39.25 m
y = 20 tan 60° = 34.64 m

The distance between men is:

d = $\sqrt{x^2+y^2} =\sqrt{39.25^2+34.64^2} = 52.35m$

Note, all numbers are rounded
