I can see that this set of lines were perpendicular until that last line that split 4 and 3. We know that a combination of 4 and 3 is equal to 90°. Plus the angle next to 1 has a measure of 57°. Those angles have the same measure. So now we know what equation to solve.

57 = 2x - 7\\57 + 7 = 2x - 7 + 7\\64 = 2x\\\frac{64}{2} = \frac{2}{2}x\\32 = x

So now we know that x = 32.

Answer:

x = 32.

Step-by-step explanation:

To solve this correctionly, I like use to make some points clear.

Opposite angles are equal. That is, angle 4 and 57° are the same.

If that be the case:

(2x - 7)° = 57°

2x = 57 + 7

2x = 64

x = 64/2

x = 32°

We can also solve it with another approach.

We know that angles on a straight line equals 180°

If that be the case, then:

Angles 3,4 and 5 are on a straight line.

Angle 3 = 33°

Angle 4 = (2x - 7)°

Angle 5 = 90°

Therefore,

90° + 33° + (2x - 7)° = 180°

123° + 2x - 7 = 180°

116° + 2x = 180

2x = 180° - 116°

2x = 64°

Divide through by 2

x = 64/2

x = 32°

Enjoy Maths.

Graph g(x)=2+|x| and it’s parent functions
matrenka [14]

The parent function is ...

... f(x) = |x|

This is the absolute value function, equal x when x ≥ 0, and equal to -x when x < 0. Its graph has the shape of a V with the vertex at the origin and "legs" of slope ±1.

The function g(x) is the same function with 2 added. The addition of 2 moves every value of f(x) up 2 units, so translates the whole graph upward by 2 units.

Use set notation to write the members of the following set, or state that the set has no members. Odd numbers between 2 and 82 t
adell [148]

Let the set of all Odd multiples of 9 between 2 and 82 be denoted by D, then, using set-builder notation,

D=\{ 18n+9 \mid n \in \mathbb{N}, 0\le n\le 4 \}

The odd multiples of 9, m, in the range 2\le m \le 82 form the set

\{9,27,45,63,81\}

Each member of the set is a term of the arithmetic progression

U_n=18n+9

where the values of n range from 0 to 4, or 0\le n\le 4

Putting these facts together, we get the result

D=\{ 18n+9 \mid n \in \mathbb{N}, 0\le n\le 4 \}
