Answer 1

Answer: 15 √ 2

Step-by-step explanation:

Equilateral triangles have three equal side lengths, three equal angles of 60 degrees, and three equal altitudes.

You would think that the height of an equilateral triangle would also be equal to it's sides, but it's not. The formula for height is: side/2 x √3

10√6 / 2 * √ 3 = 15 √ 2

The decimal form: 21.2

Please help me solve this

Answers

Answer:

to work it out:

180-110= 70

because there are two unknown angle we're gonna assume they're both the same amount. So if they are both the same and equal then we need to half 70 which will be equal to the two sided. So. 70/2= 35

So the 2 x's = 35 each

you need to put this all into an equation so:

7x-11 + 5x-2 + 2x-3 = 180 degrees

Please help will mean a lot I am stuck on this

Answers

Answer: 210 degrees

============================================================

Explanation:

Place point F on line AB such that it is to the left of point A. In other words, point A is between points F and B.

Angle CAB is 105 degrees, so this makes angle CAF to be 75 degrees. This is because 105+75 = 180. The two angles are a linear pair.

Angle CAF is the angle formed between the tangent line AB and the chord segment AC.

Due to the tangent-chord theorem, inscribed angle CEA is also 75 degrees. Note how this inscribed angle subtends the arc cut off by the chord.

The inscribed angle theorem says we can double that inscribed angle to get 2*75 = 150, which is the measure of minor arc AC.

Arc CEA is therefore 360-(minor arc AC) = 360-150 = 210 degrees

Caroline, Colin & Sarah share some money.
Caroline gets 1/9 of the money.
Colin and Sarah share the rest in the ratio 1:3.
What proportion does Sarah get?

Answers

Answer:

2 ÷ 3

Step-by-step explanation:

Let us suppose the money be 90

Since caroline gets 1 by 9 of the money i.e. 10

And, the remaining money would be distributed among Colin and sarah in the ratio of 1:3

So, the remaining money would be

= 90 - 10

= 80

So, the sarah could get

= 80 × 3 ÷ 4 ÷ 90

= 60 ÷ 90

= 20 ÷ 30

= 2 ÷ 3

if radius of circle is 4 then diameter is 8

so area of square = 8² or 64

Area of Circle = 16π

2x + y = 20
6x – 5 y= 12

Answers

Answer:

Step-by-step explanation:

We see a set of linear equations. Hence, a system of linear equations. So we solve them by process of elimination, multiplying the top equation by 5 to eliminate first such that

(2x+y=20)*5

6x-5y=12

-----------------------------------------

10x+5y=100

6x-5y=12

--------------------------------

16x = 112 .............After dividing 16 we get

x = 7

Now we plug x = 7 back into the original first equation to obtain the y value such that

2(7) + y = 20

12 + y = 20

-12 -12

------------------

y = 8

I hope this helped!

(-2x + 10) - (-6x + 5y + 12) + (x + 8y - 16)

=(-2*5 + 10) - (-6*5 + 5*-4 + 12) + (5 + 8*-4 - 16)

= (-10 + 10) - (-30 - 20 + 12) + (5 -32 - 16)

= 0 - (-38) + (-43)

= 38 - 43

= -5
