The angle for shooting laser gun should be 89.98°.

The vertical height where a tiny but horrible alien is standing is given as 443443443 meters. The horizontal distance of a men in black agent from building is given in the question as 181818 meters. So, let us assume the angle formed to be theta (θ).

Writing the formula for tan theta, that relates the given height and distance

Now, tan θ = vertical height ÷ horizontal distance

Keep the values in above mentioned equation of theta to find the angle.

tan θ = \frac{443443443}{181818}

Performing division to find the tan theta and subsequently calculate the angle

tan θ = 2438.94

θ = tan⁻¹ 2438.94

Calculating tan inverse to find the value of theta

θ = 89.98°

Therefore, the  angle for shooting laser gun by a men in black agent  should be 89.98°.

1.Point E is the midpoint. Find EF. *
Soloha48 [4]

Step-by-step explanation:

Since, Point E is the midpoint of DF

Therefore,

DE = EF

10x = 4x + 12

10x - 4x = 12

6x = 12

x = 12/6

x = 2

EF = 4x + 12 = 4*2+12 = 8 * 12 = 20

EF = 20

AB = BC

6x + 2 = 9x - 10

10 + 2 = 9x - 6x

12 = 3x

12/3 = x

x = 4

BC = 9x - 10 = 9*4 - 10 = 36 - 10 = 26

What is the value of x in the equation 1/5x – 2/3y = 30, when y = 15? 4 8 80 200
miv72 [106K]
Start with 1/5x – 2/3y = 30.  Let y = 15:      (<span>1/5)x – (2/3)(15) = 30

Then (1/5)x - 10 = 30, and (1/5)x = 40, and so x = 200 (answer)</span>

A number line is drawn left to right with integers spaced 1 centimeter apart. An ant crawls onto the number line at +3. It then
Anna11 [10]

Answer:

-1.2 cm

Step-by-step explanation:

Let's figure out where the ant is after each step.

Step 1

Start at      +3.0

Move left  <u> - 1.5 </u>

Now at       +1.5

Step  2

Start at           +1.5

Move right  <u> + 4.9 </u>

Now at         +6.4

Step 3

Start at      +6.4

Move left <u> - 7.6 </u>

Now at      -1.2

The ant is now at -1.2 cm.
