The two colors can be chosen in 3 different ways.

<h3>In how many ways can we choose two colors?</h3>

If we have a set of N elements, the number of different sets of K elements (such that the order of the K elements does not matter) is:

C(N, K) = \frac{N!}{(N - K)!*K!}

In this case, we have 3 colors, so N=3, and we want to choose 2, then K=2.

Replacing that we get:

C(3, 2) = \frac{3!}{(3- 2)!*2!} = \frac{3*2*1}{1*2*1}  = 3

The two colors can be chosen in 3 different ways.

Please help with geometry
olga_2 [115]

Presumably l and m are parallel, so n and p are transversals across parallel lines.  They'll make the obvious congruent angles and supplementary angles (add to 180 degrees) that presumably the questions will be asking about.

1. Angle 11 and angle 16.   They're what's called vertical angles from a pair of crossing lines.  Vertical angles are congruent, so m∠16 = 113°

2. Angle 1 and 3.  Those are corresponding angles on a traversal of parallels, also congruent.  m∠3 = 78°.  You got this one right, good.

3. 7 & 8.  They're what's called a linear pair, so are supplemental.  180-129=51 so m∠8 = 51°.  You probably just subtracted wrong on this one.

4. 10 & 11.   I forgot what these are called; interior angles or some such.  Anyway they're supplementary so 180-77=103.  m∠11 = 103°

5.  13 & 12.  I forgot the name here too but they're congruent so m∠12 = 59°

6. 2 & 7.  Again congruent so m∠7 = 130°  

7.  I don't know why they insist on making geometry into algebra.  Here we have angles 1 & 8, which are congruent, so

5x + 2 = 3x + 28

5x - 4x = 28 - 2

2x = 26

x = 13

Lane paints a square-shaped section of a
juin [17]

Answer:

8.66 ft

Step-by-step explanation:

A square is a shape that has an equivalent length and breadth across it’s cross section.

What this means is that measuring the length across the top and bottom will yield the same length value.

Thus, mathematically, let’s call the measured height h

The square of this height gives the area

thus;

h^2 = 75

h = √75

h = 8.660254037844

This is approximately 8.7 to one decimal place
