Answer:

$\sf\boxed{a=6}}}$

Step-by-step explanation:

Isolate the term of a from one side of the equation.

14/21=a/9

Use cross products.

$\sf{14*9=21*a}$

Solve by a.

$A=\dfrac{14*9}{21}=\dfrac{126}{21}=\boxed{\sf{6}}$

So, the final answer is a=6.

I hope this helps! Let me know if my answer is wrong or not.

Scarlett is trying to find the height of a dam. She stands 90 meters away from the dam and records the angle of elevation to the

adoni [48]

Answer:

45.55 meters

Step-by-step explanation:

I'm guessing she recorded above her height, right?

To find the height of the dam, use the tangent ratio:

$tangentX=\frac{opposite}{adjacent}$

The height of the dam is the side opposite the given angle, and this will represent x. The adjacent side (the hypotenuse is NEVER considered the adjacent side) is the distance from Scarlett to the dam. The angle of elevation is the angle of 26°. Insert the values:

$tan26=\frac{x}{90}$
