Mathematics

Allushta [10]3 years ago

Answer:

Equation to solve is x+x+120=180

Solution to equation: x=30

Step-by-step explanation:

The angles in a triangle have a sum 180 degrees.

You know one angle is 120 degrees.

If you assume another angle has a measurement of x degrees, then the remaining angle has a measurement of x degrees.  We know this because congruent means they will have the same measurement.

So we have this equation to solve:

x+x+120=180

Combine like terms:

2x+120=180

Subtract 120 on both sides:

2x=180-120

Simplify:

2x=60

Divide both sides by 2:

x=60/2

Simplify:

x=30

2(x - 2) = -4x + 44 what does x equal
Komok [63]
2(x - 2) = -4x + 44

First, expand. / Your problem should look like: 2x - 4 = -4x + 44
Second, add 4 to both sides. / Your problem should look like: 2x = -4x + 44 + 4
Third, simplify -4x + 44 + 4 to get -4x + 48. / Your problem should look like: 2x = -4x + 48
Fourth, add 4x to both sides. / Your problem should look like: 2x + 4x = 48
Fifth, add 2x + 4x to get 6x. / Your problem should look like: 6x = 48
Sixth, divide both sides by 6. / Your problem should look like: x =  \frac{48}{6}
Seventh, simplify \frac{48}{6} to 8. / Your problem should look like: x = 8

Answer: x = 8

What is the answer to C?
OleMash [197]

The diagram of the sequence of circular and square tiles gives;

a) 49

b) 84

c) Will always be odd

<h3>Which method can be used to find the order of the sequence in the pattern?</h3>

Pattern 1

Number of square tiles = 1

Number of circular tiles = 8

Total number of tiles = 9

Pattern 2

Number of square tiles = 4

Number of circular tiles = 12

Total number of tiles = 16

Pattern 3

Number of square tiles = 9

Number of circular tiles = 16

Total number of tiles = 25

  • The number of square tiles required to make pattern <em>n </em>= n²

From the diagram, the number of circular tiles on the left or right side of the square tiles are 2 more than the number of square tiles, while the number of circular tiles on the top or bottom are the same as the number of square tiles, therefore;

  • Number of circular tiles = 2•(n + 2) + 2•n

a) The number of square tiles required to make pattern number 7 = 7² = 49

b) The number of circular tiles needed to make pattern number 20 = 2 × 20 + 2 × (20 + 2) = 84

c) The total number of circular tiles is always even while the number of square tiles has the same characteristics (even or odd) as the pattern number

  • Even + Odd = Odd
  • Even + Even = Even

When the pattern number is odd, the total number of tiles will always be odd. The correct option is therefore;

B. Will always be odd
