Answer:

The length of the hypotenuse is 4.1 in

Step-by-step explanation:

By definition, the sine of an angle is:

sin(x) = \frac{opposite\ side}{hypotenuse}

In this case they tell us that the opposite side measures 4 inches and the angle x measures 80 °.

With this information we can find the length of the hypotenuse h

sin(80\°) =\frac{4}{h}\\\\h = \frac{4}{sin(80\°)}\\\\h = 4.062\ in

Finally the length of the hypotenuse is 4.1 in

Here is Laila’s graph from the previous screen.
lidiya [134]

Answer:

y=-1/3x+8

Step-by-step explanation:

There is no need for any specific answers, but here is one that could logically work out. Since the graph is going left/down, it has a negative slope, so -1/3 would be reasonable. The graph doesn't cross the origin and crosses above it, so this equation must have a positive 'b' value. In this case, I chose 8. y=-1/3+8 could represent Laila's graph.

Find the area of a quarter circle with the radius of 6cm
Ronch [10]

Answer:

28.27cm³

Step-by-step explanation:

Area of a circle:

A=\pi r^2

First, find the area of a full circle with this given radius:

\rightarrow A=(3.14159)(6)^2\\\rightarrow A=(3.14159)(36)\\\rightarrow A=113.09734\\

Now, to find the radius of a quarter circle with the same radius, just divide by 4:

\rightarrow A = \frac{113.09734}{4}\\\rightarrow A = 28.27433

The radius of the quarter circle is about 28.27cm³
