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 =
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°.

Answer:
(a) Mrs. Johnson’s class sold 26 cookies, Mr. Smith’s class sold 27 popcorn.
(b) Mrs. Johnson’s class earned Mr. Smith’s class earned
Hence, Mrs. Johnson’s class earned more.
(c) Mrs. Johnson’s class earned more.
Step-by-step explanation:
Let x be the number of cookies Mrs. Johnson’s class sold and y be the number of popcorn Mr. Smith’s class sold.
(a) If Mrs. Johnson’s class sold x cookies for $2.50 each, then they earn $2.50x. If Mr. Smith’s class sold y popcorn for $1.50 each, then they earn $1.50y. In total, $2.50x+$1.50y=$105.50.
Together, the classes sold 53 items, then x+y=53.
You get the system of two equations:

(b) Mrs. Johnson’s class earned Mr. Smith’s class earned
Hence, Mrs. Johnson’s class earned more.
(c) Mrs. Johnson’s class earned more.
