Let the third angle of the triangle be y.

y + 64° + 45° = 180° (angle sum of triangle is 180°)

x + y = 180° (angle of a straight line is 180°)

Notice that they both equal 180°. This means that they are the same thing, hence:

y + 64° + 45° = x + y

Since y = y, it is not necessary to write them down. Remove y from both sides of the equation:

64° + 45° = x

Surprise! exterior angle = sum of interior opposite angles.

I hope this clears up any confusion you might have. If not, feel free to leave a comment with your question.

A customer pays $3.27 for oranges and $4.76 for pears. How many pounds of fruit does the customer buy?

Take 3.27 and divide that by 1.09  (for the oranges)
3.27/1.09=3lbs. of oranges
then take 4.76 and divide that by 1.19       (for the pears)
4.76/1.19=4lbs. of pears
add 4+3 to get how many lbs. in all
4+3=7

The figure shows the front side of a purse in the shape of a trapezoid.
attashe74 [19]
For this case, what you must do is take out the area of two triangles and add it to the area of a rectangle to find the total area.
 We have then:
 Triangle area:
 A = (1/2) * ((13-9) / (2)) * (10) = 10 in ^ 2
 Rectangle area:
 A = (9) * (10) = 90 in ^ 2
 Total area:
 At = 2 * (10) + 90 = 110 in ^ 2
 answer:
 110 in²

Jessica rolled two six-sided number cubes with sides numbered 1 through 6. The list below shows the possible outcomes when rolli
timurjin [86]
The list of possible outcomes in the question is totally incomprehensible.  But from our vast experience with questions like this and dice in general, we know there are 36 of them.

Now, here are all the ways to roll a total of 9:

3, 6
6, 3
4, 5
5, 4

Four of the 36 possible rolls result in a 9.
So the probability (with honest dice) is 4/36 = 1/9 = 11.1% .

Please help me on number 31 please I beg you
Brums [2.3K]
Assuming the garden is a rectangle, the area is equal to length times width.


So 20x = 760.

Divide both sides by 20.

x = 760/20 = 38 ft

What is the mode of the data set?
strojnjashka [21]

The data set is

20

32, 34, 36

40, 42, 44, 48

55

65

We can see that each value only shows up one time. Therefore there is no mode. To have a mode, we need to have a value show up more than once, and it must be the most frequent value. For example, the set {1,2,3,3,4} has a mode of 3 since it shows up twice, the most of any value in that set. However we don't have that occur for the data set your teacher gave you.

<h3>Final Answer: There is no mode for this data set</h3>
