The formula is base*height.
This is because in a parallelogram (a slanted one), you can multiply base*height and the triangle from the other side can be moved.
Which is why it's also the formula for rectangle and squares since they are also parallelograms

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.

▹ Answer

x = -7

▹ Step-by-Step Explanation

-3x - 4(4x - 8) = 3(-8x - 1)

Distribute

-3x - 16x + 32 = -24x - 3

Collect like terms

-19x + 32 = -24x - 3

Move variable to the left and change the sign

-19x + 24x + 32 = -3

Collect like terms

5x = -3 - 32

Calculate

5x = -35

Final Answer

x = -7

Hope this helps!
