Question

The picture below shows a right-triangle-shaped charging stand for a gaming system:

Answer 1

Which expression shows the height, AC, of the charging stand?
3 divided by cos 50 degrees
3 tan 50°
3 divided by tan 50 degrees
3 cos 50°

Answer 5

So if you wanted to solve that triangle that is shown, what would be the first step?

Answer 6

You MUST memorize the Right Triangle Definitions of Sine, Cosine, and Tangent. The last will solve this problem.

Answer 7

we use SOHCAHTOA and wouldn't it be the tangent formula?

Answer 8

Yes, it would so your equation would look like:\[\tan 50=\frac{ x }{ 3 }\]Does that make sense?
And then, all you would do is simply that. What would that look like simplified?

Answer 9

Thank you!!! the question only asks for this
3 divided by cos 50 degrees
3 tan 50°
3 divided by tan 50 degrees
3 cos 50°

Answer 10

so it would be C?

Answer 11

So when you simplify this equation, you need to isolate the x. To do that you would multiply each side by 3, making your answer \[3\times \tan50\]
Also known as: B
C was there to trick you. :D

Answer 12

The question asks for you to understand the right triangle definition of the tangent. Use the expression given above and find it.

Answer 13

ohhh ok thank you !!!
