<h3>Answer: Vertical angles</h3>

Explanation:

Ignore the ray that angles 2 and 3 are adjacent to. It might help to copy the drawing but erase that ray in question. All we really care about is the X shape the two lines form along with angles 1 and 4. These two angles are opposite one another. We consider them vertical angles. They don't have to align vertically. They simply have to be opposite one another like this in this X configuration. Vertical angles are always congruent to one another.

What is 3+0.5(4a+8)=9-2a is your solving for (a).
Nady [450]

Answer:

a = 1/2

Step-by-step explanation:

<u>Step 1:  Distribute </u>

<u />3 + 0.5(4a + 8) = 9 - 2a

3 + (0.5 * 4a) + (0.5 * 8) = 9 - 2a

3 + 2a + 4 = 9 - 2a

<u>Step 2:  Combine like terms </u>

<u />(3 + 4) + 2a = 9 - 2a

7 + 2a = 9 - 2a

<u>Step 3:  Subtract 7 from both sides </u>

<u />7 + 2a - 7 = 9 - 2a - 7

2a = 2 - 2a

<u>Step 4:  Add 2a to both sides </u>

<u />2a + 2a = 2 - 2a + 2a

4a = 2

<u>Step 5:  Divide both sides by 4 </u>

<u />4a / 4 = 2 / 4

a = 1/2

Answer:  a = 1/2

If 4x is one factor of 4x^2-12x, what is the other factor?
Zepler [3.9K]
If you factor 4x²-12x, you can divide 4x from each term.

4x² ÷ 4x = x
-12x ÷ 4x = -3

Therefore, the other term becomes (x-3) because 4x(x-3) = 4x²-12x

2.) Find the length of the unknown side. Round your answer to the nearest tenth.
Juli2301 [7.4K]

Answer:

14.1

Step-by-step explanation:

Hey There!

This is a right triangle so we have to use the Pythagorean Theorem to solve for the missing side

given the hypotenuse and a leg we do

hypotenuse^2-given.leg^2

15^2-5^2=?^2\\15^2=225\\5^2=25\\225-25=200\\\sqrt{200} =14.1421356

then we just round to the nearest tenth and get that

?=14.1
