Answer:

210 or 330 degrees for angles between 0 and 360 degrees.

Step-by-step explanation:

Arcsin (1/2) = 30 degrees if the angle is in the first quadrant.

The sine is negative in the third and fourth quadrants so arcsin (-1/2)

= 210 or 330 degrees for angles between 0 and 360 degrees.

Angle O=64

Side m=7.3159882(rounded if needed)

Side n=16.68902(round if needed)

We are given

Angle M which equal 26.

Angle N equals 90 degrees

Side MN which equal 15.

We are asked to find all the missing elements of the triangle.

Angle O can be found using triangle interior theorem so we can add 90+26+x =180 to find the value that satisfies the x value.

$90 + 26 + x = 180$

$116 + x = 180$

$x = 64$

Angle O=64 degrees

We can find side m by doing law of sines.

$\frac{on}{ \sin(26) } = \frac{mn}{ \sin(64) }$

$\frac{on}{ \sin(26) } = \frac{15}{ \sin(64) }$

$on = \frac{15}{ \sin(64) } \times \sin(26)$

which is 7.315(round if neeeded).

We can find side n using pythagorean theorem,

${15}^{2} + {7.3}^{2} = {n}^{2}$

$225 + 53.29 = {n}^{2}$

$\sqrt{278.29}$

Side n=16.689(round if needed)

Fatima plotted one side of a heptagon on a grid. the points (-8,1) and (-8,8) are joined to form a side of the heptagon. Fatima

Reil [10]

The general formula for the distance between two points is

$d(A,B) = \sqrt{(A_x-B_x)^2 + (A_y-B_y)^2}$

Anyway, if A and B have the same x or y coordinates, this formula can be simplified. For example, in this case the two points have the same x coordinate of -8, so the following part of the formula simplifies:

$(A_x-B_x)^2 = (-8-(-8))^2 = (-8+8)^2 = 0^2 = 0$

So, we're left with

$d(A,B) = \sqrt{(A_y-B_y)^2}$

but the square root of a square is the absolute value of the object being squared:

$d(A,B) = \sqrt{(A_y-B_y)^2} = |A_y-B_y|$

which is this case means $|1-8| = |-7| = 7$

which is the correct length of the side.

The figure below shows a shaded rectangular region inside a large rectangle: (pic)

mariarad [96]

Answer:

Step-by-step explanation:

Probability of falling NOT in the shaded region is "area of white region" divided by "area of whole rectangle (big one)".

Area of whole rectangle:

Area of rectangle = length * width = 10 * 5 = 50

Area of White Region:

First, area of shaded region = length * width = 4 * 2 = 8

Now,

Area of white region = area of whole rectangle - area of shaded rectangle

Area of white region = 50 - 8 = 42

Hence, probability is $\frac{42}{50}=0.84$

0.84 = 84%

Answer choice D is right.
