Trigonometric functions: what is the value of x?
Airida [17]

Answer:

x ≈ 19.7

Step-by-step explanation:

Using the sine ratio in the right triangle.

sin66° = \frac{opposite}{hypotenuse} = \frac{18}{x} ( multiply both sides by x )

x × sin66° = 18 ( divide both sides by sin66° )

x = \frac{18}{sin66} ≈ 19.7 ( to the nearest tenth )

Find the area of triangle DEF with vertices D(-1,2), E(3,-2) and F(-2,-2).*
Veronika [31]

Answer:

<em>The area of the triangle DEF is 10.</em>

Step-by-step explanation:

<u>Area of a Triangle:</u>

A triangle of base B and height H (both must be perpendicular) has an area of:

\displaystyle A=\frac{BH}{2}

The image below shows the triangle formed by the points DEF. It's important to notice the points E and F lie on the same horizontal line because they both have the same y-coordinate.

This fact simplifies the calculations since we can easily compute the length the of base as the difference of their x-coordinates:

B=3-(-2)=3+2=5

Being the base of a horizontal line, the height of the triangle can be calculated as the difference of y-coordinates of D and the height of that line.

H=2-(-2)=4

With these two values, we calculate the area:

\displaystyle A=\frac{5*4}{2}=10

The area of the triangle DEF is 10.

Solve (2/3)-(1/x)=5/6
Keith_Richards [23]
\frac{2}{3} - \frac{1}{x} = \frac{5}{6}   Multiply both sides by 3
2 - \frac{1(3)}{x} = \frac{5(3)}{6}   Simplify the numerators
2 - \frac{3}{x} = \frac{15}{6}   Multiply both sides by 6
12 - \frac{3(6)}{x} = 15   Simplify the numerator
12 - \frac{18}{x} = 15   Multiply both sides by x
12x - 18 = 15x   Subtract 12x from both sides
       -18 = 3x    Divide both sides by 3
        -6 = x      Switch the sides to make it easier to read
         x = -6

Check your answer by plugging -6 in for the x in the original problem:

\frac{2}{3} - \frac{1}{x} = \frac{5}{6}   Plug in -6 for x
\frac{2}{3} - \frac{1}{-6} = \frac{5}{6}   Change \frac{2}{3} to \frac{4}{6} so all denominators are the same
\frac{4}{6} - \frac{1}{-6} = \frac{5}{6}   Change \frac{1}{-6} to  \frac{-1}{6} for easier work
\frac{4}{6} - \frac{-1}{6} = \frac{5}{6}   Subtract the numerators (4 - (-1) )
\frac{5}{6} = \frac{5}{6}

So, x = -6 .
