Answer:

Step-by-step explanation:

In a parallelogram, the opposite sides are equal and parallel.

The opposite angle of a parallelogram are equal. The consecutive angles of a parallelogram are supplementary. This means that their sum is 180 degrees. Since the two supplementary angles are (3x + 10) degrees and (x - 30) degrees, it means that

3x + 10 + x - 30 = 180

3x + x = 180 - 10 + 30

4x = 200

x = 200/4 = 50

The measure of one angle is

x - 30 = 50 - 30 = 20 degrees

The measure of the other angle is

3x + 10 = 3 × 50 + 10 = 160 degrees

Answer:

x = 50°

Step-by-step explanation:

3x + 10 + x - 30 = 180

4x-20= 180

4x=180+20

x= 200/4

x= 50

A standard deck has 52 cards consisting of 26 black and 26 red cards. Three cards are dealt from a shuffled deck without replace

Allisa [31]

They aren't independent since the probability uses all the cards in the deck

So at the first deal we have the chance of 26/52 of getting a red card, at the second deal we have the chance of a 25/51 of getting another red card, so they aren't independent

Find the area of each figure. round to the hundredths place when necessary

notsponge [240]

Answer:

115.48 $m^{2}$

Step-by-step explanation:

This shape can be split into two distinct shapes

Two halves of a semi circle, and a rectangle in between

Circle:

Putting both halves of the semi circle together will give you a full circle. The diameter of the circle is given (7m).

The area of a circle is A = π $r^{2}$

The radius, r, is half of the diameter, so 7 / 2 = 3.5m

A = π $r^{2}$

A = π * $3.5^{2}$

A = 38.38 $m^{2}$

Rectangle:

The area of a rectangle is A = h b

The height, h, is known at 7m

The base, b, can be found by removing the length from the dot to the end of the semi circles. This length is the radius of the semi circles, 3.5m

Removing the radius from the total length given

18 - 3.5 - 3.5 = 11m

The base is 11m

A = h b

A = 7 * 11 = 77 $m^{2}$

Total Area = Circle area + Rectangle area

Total Area = 38.38 + 77 = 115.48 $m^{2}$
