  • Alternate Interior Angles: They are angles that are diagonal from each other. They are formed by two parallel lines being crossed by a transversal, and <u>are congruent to each other.</u>
  • Linear Pair: Pair of adjacent angles formed when two lines intersect. <u>They are supplementary, or add up to 180°</u>

Starting with ∠2 , <u>∠2 is an alternate interior angle to 113° angle.</u> Since Alternate Interior angles are congruent to each other, <u>this means that ∠2 is 113°</u>

Next with ∠5, <u>∠5 and 113° angle are a linear pair.</u> This means that they are supplementary, or add up to 180°. Using what we know, we can solve for ∠5's degree as such:

\angle\ 5 + 113\text{\textdegree} = 180\text{\textdegree}\\\angle\ 5=67\text{\textdegree}

<u>∠5 is 67°</u>

If using the method of completing the square to solve the quadratic equation x2 + 3x - 17 = 0, which number would have to be add
MatroZZZ [7]

Answer:

Step-by-step explanation:

To solve using completing square, we need to write the equation as x2+3x=17.

The next step is to add a number such that the square can be completed. The number must be equal to (b/2a)^2, so here it will be (3/2)^2 = 9/4

The equation then becomes x2+3x+(9/4)=17+(9/4).

Solving it further will get you the final answer

6 - 2/3 (x+5) = 4x solve algebraically for the exact value of x
luda_lava [24]

Answer:

x = 2

Step-by-step explanation:

1 - Rewrite

6 - 2/3 (x+5) = 4x

2 - Distribute

6 - 2/3x + 10/3 = 4x

3 - Combine like terms and get x alone

6 10/3 - 2/3x = 4x

           +2/3x  +2/3x

          6 10/3 = 4 2/3x

------------------------------- Convert to decimals

6.3333333333.... = 4.333...x

-------------------------------- Divide both sides by 4.33...x

2 = x

Hope this helps :)
