Answer:

−15a

Step-by-step explanation:

Let's solve for b.

11a+

=6a

Step 1: Add -11a to both sides.

11a+

b+−11a=6a+−11a

b=−5a

Step 2: Divide both sides by 1/3.

−5a

b=−15a

Answer:

b=−15a

Answer:

The distance from he ball to the goal is 11.85 feet (Approx) .

Step-by-step explanation:

As given

The angle of elevation from a soccer ball on the ground to the top of the goal is 34° .

If the goal is 8 feet tall.

Now by using the trigonometric identity .

$tan \theta = \frac{Perpendicular}{Base}$

As shown in the diagram given below

$\theta = 34^{\circ}$

Perpendicular = AB = 8 feet

Base = BC

Put all the values in the identity .

$tan\ 34^{\circ} = \frac{AB}{BC}$

$tan\ 34^{\circ} = \frac{8}{BC}$

$tan\ 34^{\circ} = 0.675\ (Approx)$

$BC = \frac{8}{0.675}$

BC = 11.85 feet (Approx)

Therefore the distance from he ball to the goal is 11.85 feet (Approx) .

To find the area of the triangle, you need to do 9*8=72 then divide by 2 to get 36. to find the area of the square you do 5*5=25. subtract 36-25 to get 11. the area of the unshaded region is 11 centimeters squared.
