The answer is 42 because the small blue box in the corner is 90 degrees so you minus that by 132 degrees and get 42 degrees

Evaluate the exact value: tan(pi/6)

Sedbober [7]

Pi/6 = 180°/6 = 30°

This produces a triangle that has 30-60-90 angles.

Its short leg will measure = y = sinΘ
Its long leg will measure = x = √1-y² = sin(2Θ)
Its hypotenuse will measure = 1

Tangent Θ = opposite / adjacent or short leg / long leg
Tan(pi/6) = 1/3 √3

The diagonals of a rhombus intersect at the point (0,4). If one endpoint of the longer diagonal is located at point (4,10), wher

Wewaii [24]

Answer:

The other endpoint is located at (-4,-2)

Step-by-step explanation:

we know that

The diagonals of a rhombus bisect each other

That means-----> The diagonals of a rhombus intersect at the midpoint of each diagonal

The point (0,4) is the midpoint of the two diagonals

The formula to calculate the midpoint between two points is equal to

$M=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})$

we have

$M=(0,4)$

$(x_1,y_1)=(4,10)$

substitute

$(0,4)=(\frac{4+x_2}{2},\frac{10+y_2}{2})$

<em>Find the x-coordinate $x_2$ of the other endpoint</em>

$0=\frac{4+x_2}{2}$

$x_2=-4$

<em>Find the y-coordinate $y_2$ of the other endpoint</em>

$4=\frac{10+y_2}{2}$

$8=10+y_2$

$y_2=-2$

therefore

The other endpoint is located at (-4,-2)

Answer:
x = 3

Explanation:
Let's first start with the front triangle.
This one is an isosceles right-angled triangle. This means that it has special side lengths of: s , s and s√2 with s√2 being the hypotenuse.
Since we have the hypotenuse = 6√2 units
Therefore, each of the other two sides would be of length = 6 units

Now, let's consider the side triangle.
This one is also a right-angled triangle. This means that special trigonometric functions can be applied.
These functions are:
sin (θ) = opposite / hypotenuse
cos (θ) = adjacent / hypotenuse
tan (θ) = opposite / adjacent

Now, we have:
θ = 60°
adjacent side = x
hypotenuse = 6 units (calculated from the previous step)

Substitute with the givens in the cos function to get the value of x as follows:
cos (60) = x / 6
x = 6 * cos(60)
x = 3 units

Hope this helps :)
