Solve system of linear equation with substitution

Blizzard [7]

Answer:

x=1, y=2

Step-by-step explanation:

solve by substitution so substitute x= 6y-11 in the next equation

3 (6y-11) - 2y = -1

18y -33-2y = -1

16y = 33-1

y= 32/16 =2

x= 6y -11 = 6*2 -11 = 12 -11 = 1

The height of the Eiffel Tower is 1050 feet. From the top, the angle of depression to a soccer ball on the ground is 20 degrees.

mihalych1998 [28]

Since the angle of depression from the Eiffel tower is congruent to the angle of elevation from the soccer ball, the angle of elevation from the soccer field is 20°

Now, we can use the trigonometric function tangent to find the distance from the soccer ball to the base of the Eiffel Tower:
 $tan( \alpha )= \frac{opposite.side}{adjacent.side}$
$tan(20)= \frac{1050}{a}$
$a= \frac{1050}{tan(20)}$
$a=2884.85$

We can conclude that the distance from the soccer ball to the base of the Eiffel Tower is 2884.85 feet.
