Answer:

  x = 11

Step-by-step explanation:

The external angle is half the difference of the subtended arcs. The smaller arc is shown as 86°. The larger arc will be the difference between 360° and the two arcs shown.

  larger arc = 360° -74° -86° = 200°

So, the external angle is ...

  4x +13 = (200 -86)/2 = 57

  4x = 44 . . . . . . . . . . . . subtract 13 from both sides

  x = 11 . . . . . . . divide by 4

A triangle has one angle that is three times the size of another, and a third angle that is 16degrees smaller than the larger of
Dafna11 [192]

Answer:

26, 68 and 84

Step-by-step explanation:

Let the angle that is three times smaller than another be X.

Since the angle sum of a triangle is 180 degrees, we can form the following equation:

X + 3X + (3X- 16) = 180

Now we can simplify this equation:

7X - 16 = 180

7X = 196 (add 16 to both sides)

X = 196/7

X = 28

Therefore, the smallest angle is 28 degrees.

And from here we can figure out the other angles as they are 3x28 and 3x28 - 16.

So the three angles are 28 degrees, (3x28-16) 68 degrees, and (3x28) 84 degrees.

Someone answer 1-8 please! (Please do help!)<br> QUESTION: Find each quotient.
Zinaida [17]
Sorry, but I generally respond to only 1 or 2 problems when someone gives me a long list of homework.  It would take you just a little longer to post one problem at a time.
                                                                             75                 5       -375
Let's look at #5:     75 / (-1/5)   is the same as  -------- = 75 * ------ = ---------                                                                                         -1                -1         1
                                                                              ---
                                                                                5

and this is equivalent to -375 (answer to #5)

Show calculations for each of the ratio table
Sladkaya [172]

Answer:

From left to right:

3, 30, 20

Step-by-step explanation:

Start by determining the ratio of yellow to red paint. Use the column where both amounts are given:

yellow to red = 2 to 6 = 1 to 3

2 to 6 the same as 1 to 3 when reduced, by dividing both sides by 2.

This means yellow paint is a third of red paint. Backwards, red paint is three times yellow paint.

To go from yellow to red, do yellow X 3.

To go from red to yellow, do red ÷ 3.

Column 1:

1 X 3 = 3

Column 3:

10 X 3 = 30

Column 4:

60 ÷ 3 = 20

The ratios are:

1 to 3

2 to 6

10 to 30

20 to 60
