If x is equal to 9 and y is equal to -3, then what is the value of…….? x - 9y - 3x + 6y -13?

Vesnalui [34]

We are given –

x =9
y = -3

Now put the values –

$\qquad$ $\twoheadrightarrow\bf x - 9y - 3x + 6y -13$

$\qquad$ $\twoheadrightarrow\sf 9 -(9 \times -3) -(3 \times 9) +(6 \times -3) -13$

$\qquad$ $\twoheadrightarrow\sf 9 + 27 -27 -18 -13$

$\qquad$ $\twoheadrightarrow\sf 9 +\pink{\cancel{27}}-\pink{\cancel{27}} -31$

$\qquad$ $\twoheadrightarrow\bf-22$

Henceforth, value of x - 9y - 3x + 6y -13 is -22.

A tiny but horrible alien is standing at the top of the Empire State Building (which is

Leto [7]

Answer:

87.7 degrees.

Step-by-step explanation:

In triangle ABC, attached.

The height of the building |AB|=443 meters

The distance of the agent across the street , |BC|=18 meters

We want to determine the angle at C.

Now,

$Tan C=\dfrac{|AB|}{|BC|} \\C=arctan (\dfrac{|AB|}{|BC|} )\\=arctan (\dfrac{443}{18} )\\=87.67^\circ\\\approx 87.7^\circ $(correct to the nearest tenth)$

The agent should sfoot his laser gun at an angle of 87.7 degrees.
