The clouds are 226.68 meters above the spotlight.

Step-by-step explanation:

Step 1:

The angle measuring device is 65 meters from the spotlight and the angle of elevation from the ground to the spot of light is 74°.

So a right-angled triangle can be formed using these measurements. The angle of the triangle is 74° while the opposite side of the triangle measures x meters while the adjacent side of the triangle measures 65 meters.

We need to calculate the opposites side's length of the triangle.

Step 2:

Since we have the adjacent side's length and need to calculate the opposite side's length we use the tan of the given angle.

The opposite side of the triangle = x meters.

$\tan \theta = \frac{oppositeside}{adjacentside} = \frac{x}{65}.$

$tan 74 = 3.487, x = 3.487(65) = 226.07.$

So the spot of light is 226.07 meters above from the spotlight.

Bobby describes two lines to Frank, telling him that beginning at point A, line #1 goes up 3 units and to the right 8 units, whi

rodikova [14]

When a line changes position from one point to another, the movement is referred to as transition.

Bobby does not have enough information to make a valid conclusion.

The movements of the lines are given as:

Line 1: 3 units up and 8 units right

Line 2: 8 units down and 3 units right

The given information only describes the movement of both lines, but does not give details about the initial relationship between the lines.

Hence, no valid conclusion can be made with the given information.
