In ΔWXY, w = 880 cm, ∠X=33° and ∠Y=38°. Find the length of y, to the nearest centimeter.
vladimir2022 [97]

Answer:

y\approx573cm

Step-by-step explanation:

First, take a look to the picture that I attached,  however please note the triangle is not drawn to scale, the figure is just to provide visual aid. As you can see the value of \angle W =109^{\circ} this is because of the sum of the interior angles in a triangle is always equal to 180°. So:

\angle W + \angle X + \angle Y =180\\\\\angle W = 180- \angle X -\angle Y\\\\\angle W =180-38-33\\\\\angle W=109

Now, we can use the law of sines, which states:

\frac{w}{sin(W)} =\frac{x}{sin(X)} =\frac{y}{sin(Y)}

Hence:

\frac{w}{sin(W)} =\frac{y}{sin(Y)}\\\\\frac{880}{sin(109)} =\frac{y}{sin(38)}\\\\Solving\hspace{3}for\hspace{3}y\\\\y=\frac{880*sin(38)}{sin(109)} \\\\y=572.9999518\approx 573 cm

You graph a rectangle on a coordinate plane that has vertices (0,0), (3,0), (0,2), and (3,2). You then rotate that figure 360 de
wolverine [178]
From the points given we know that the rectangle is 3 points wide and 2 points tall. If we rotate it 360^{\circ} around the x axis then we will receive the lying cyllinder which will be 3 points tall and 2 points wide (so its radius is 2/2 = 1 point). Now we can find the surface area of the cyllinder using appropriate formula:
A=2\pi r^2 + 2\pi rh=2\pi*1^2 + 2 \pi * 1 * 3=2\pi + 6\pi=8\pi\approx 25.13
