Answer:

27 degrees      

Step-by-step explanation:

12: 180 = 3x - 17 + x + 40 + 2x - 5

180 = 6x + 18

180 - 18 = 6x

162 = 6x

x = 27 degrees

Answer:

Remember the Triangle Angle Sum theory which states that all angles of a triangle add up to 180˚. With this, make the following equation:

(3x-17) + (x + 40) + (2x - 5) = 180

Get rid of parenthesis

3x - 17 + x + 40 + 2x - 5 = 180

Group like terms:

3x + 2x + x + 40 - 17 - 5 = 180

Simplify

6x + 18 = 180

Subtract 18 from both sides.

6x + 18 - 18= 180 -18

6x= 162

Divide both sides by 6

6x/6= 162/6

x= 27

Whats equlvlent to 3√6
Firlakuza [10]

Answer:

Important: 3

6

looks like a fraction, but it is actually an improper fraction.

There is an infinity number of equivalent fractions to 3

6

.

To find an equivalent fraction to 3

6

, or to any other fraction, you just need to multiply (or divide, if the fraction is not yet reduced), both the numerator and the denominator of the given fraction by any non-zero natural number. For example:

By dividing the original fraction by 3, we get:

3 ÷ 3

6 ÷ 3

= 1

2

By multiplying the original fraction by 2, we get:

3 × 2

6 × 2

= 6

What is the equation in vertex form of the quadratic function with a vertex at (-1, -4) that goes through (1, 8)?
cestrela7 [59]

Answer:

y = 3(x+1)^2 - 4

Step-by-step explanation:The general form of the equation of a quadratic function whose vertex is (h,k) and whose leading coefficient is a is:

y - k = a(x-h)^2, or

y      = a(x-h)^2 - k

Substituting the coefficients of the vertex (-1, -4), we get:

y      = a(x + 1)^2 - 4

Substituting the coordinates of the given point, (1,8), we get:

8      = a(1+1)^2 - 4, which simplifies to:

8      = a(2)^2 - 4, or

8  = 4a - 4.  Then 4a = 12, and a = 3.

Thus, the desired equation is y = 3(x+1)^2 - 4 (answer j).
