Answer:

Angle formed by the sector measuring x% will be 126°.

Step-by-step explanation:

Since, sum of all sectors formed in a circle is 100%.

By adding the measures of all the sectors,

x + x + 21 + 9 = 100

2x + 30 = 100

2x = 70

x = 35%

Now we know sum of all the central angles formed at the center of a circle = 360°

Therefore, angle formed by x% = 360° × 35%

                                                    = \frac{360\times 35}{100}

                                                    = 126°

Consider the two triangles.
brilliants [131]

The ratios StartFraction U V Over Z Y EndFraction , StartFraction W U Over Z X EndFraction , and StartFraction W V Over X Y EndFraction are equivalent.

<h3>Similarity theorem of triangles</h3>

For two triangles to be similar, the ratio of the measure of similar sides of the triangle must be equal to a constant known as a scale factor.

From the given figures, the expression that can be used to prove that the triangles are similar is as shown;

UV/ZY = WU/ZX = WV/XY

Hence the correct option is to show that the ratios StartFraction U V Over Z Y EndFraction , StartFraction W U Over Z X EndFraction , and StartFraction W V Over X Y EndFraction are equivalent.

Can someone please help me with the his question!!!!
almond37 [142]

Answer:

-6x - 13 = 10

Step-by-step explanation:

To solve this question, you just have to simplify the values

3(x - 3) - (9x + 4) = 10

3x - 9 - 9x - 4 = 10

-6x - 13 = 10

If you have any questions, let me know in the comments. If you could mark this answer as the brainliest, I would greatly appreciate it! :D

The size of the red squirrel population has decreased exponentially
aalyn [17]

Answer:

The size of the population of red squirrels in the UK at the start of 2010 is 3772

Step-by-step explanation:

At the start of 2016 , No. of squirrels = 10000

The rate of decrease is 15% per year.

So, No. of squirrels after x years = 10000(1-0.15)^x

We are supposed to find the size of the population of red squirrels in the UK at the start of 2010.

So,No. of squirrels after 6 years = 10000(1-0.15)^6=3771.49

Hence the size of the population of red squirrels in the UK at the start of 2010 is 3772

Find the unknown value in proportion 2.3/6.7 = 4.6/x <br> a)13.4<br>b)20.1<br>c)1.6<br>d)3.4
Dominik [7]

2.3/6.7 = 4.6/x

using cross products

2.3*x = 6.7 * 4.6

divide by 2.3

x = 6.7 * 4.6 / 2.3

x = 6.7 * 2

x = 13.4

Choice A
