A skate ramp is 4.2 meters long. It rises up 1.7 meters. What’s is the angle of elevation to the nearest tenth of a degree?

Explanation:
We view the ramp as a right triangle. The hypotenuse is 4.2 and the vertical side .7, which is opposite the angle
θ
we seek.

I'm going to finish the problem but I'll note if we were actually building the ramp we don't need to know the angle; this sine is sufficient.

which I think is a pretty steep ramp for a wheelchair.
There will be another inverse sine that is the supplementary angle, around

, but we can rule that out as a value for a ramp wedge angle.

What relationship do the ratios of sin x° and cos y° share?
puteri [66]

Answer:

The ratios are both identical (3/5 and 3/5).

Step-by-step explanation:

sin x° is equivalent to O/H, or the opposite/hypotenuse sides of the triangle. Therefore:

sin x° = 3/5.

cos y° is equivalent to A/H, or the adjacent/hypotenuse sides of the triangle.

cos y° = 3/5.

\frac{3}{5} =\frac{3}{5}

The ratios are identical.

Imagine you find a property with a market value of $330,000, and the seller agrees tosell it to you for $275,000. You flip the p
Taya2010 [7]

First let's calculate the profit in the deal, subtracting the market value and the selling value:

330000-275000=55000

So the profit is $55,000.

Now, calculating the fee of 10% of the profit, we have:

10\text{\% of }55000=0.1\cdot55000=5500

So the fee is $5,500, therefore the correct option is the fourth one.
