5) Solve for x and find both angle measurements -

Answers

Well we know that this is a 90° angle, so 2x and x must equal 90°. Knowing this info we can create an equation to solve for x:

90 = 2x +x
90 = 3x
90/3= 3x/3
30 = x

Now let’s look back at the angles, the first one is just x, so it would be 30° but the second one is 2x so it would be 30° x 2 which would make it 60°
Hope this helps!

Answer:

x = 30

(2x)° = 60°

x = 30°

Step-by-step explanation:

The two angles combined is a right angle, and a right angle is 90°, so we can put that into this equation:

2x + x = 90 which is the same as 3x = 90 because 2x + x = 3x

3x = 90

divide both sides by 3 so you can get x by itself

3x divided by 3 = x

90 divided by 3 = 30

you get x = 30

since x = 30, 2x is the same as 2 times 30, and that is 60.

3x−5(x−6)=2(10−x)
What does x equal?

Answers

Answer:

Step-by-step explanation:

First you would have to distribute -5 through the first set of parentheses which would make the equation 3x-5x+30=2(10-x). Then you would have to distribute 2 through the second pair of parentheses which makes the equation 3x-5x+30=20-2x. You would then have to collect like terms which gets the equation to -2x+30=20-2x. You then cancel equal terms which makes the solution 30=20 so the statement is false.

Step-by-step explanation:

» Concepts

To name an angle, you MUST include the vertex either in the middle or have it standing by itself. To clarify, you can either call this angle ∠G, ∠HGI, or ∠IGH because they all include the vertex, G, in the middle or by itself. You put ∠HIG, which is incorrect because the vertex is not I.

Write an improper fraction using the following criteria:

• an improper fraction
• the value is between 1 and 5
• the denominator is 7

Answers

Let's take this number:

28/7

WHY this number fits the criteria?

It's an improper fraction since the numerator is higher than the denominatorIt's value IS between 1-5 because 28 divided by 7 = 4, 4 is in middle of 1-4The denominator IS 7

How did I find this number?

I did 7x4 to get the numerator, so that it would be between 1-5And I made sure that it's an improper fractionAnd also, I made sure that the denominator is 7

Hence, 28/7 can be one answer

(note: there are MANY answers to this question)

21/7

Divide 21(numerator) by 7 (denominator) and you get 3 which is between 1 and 5

The area of a triangle is how much space is in the triangle. The formula for the area of a triangle is [tex]\frac{1}{2} bh[/tex], where b = base and h = height.

» Application

We're given the area as 10 cm² and the base as 5 cm. Thus, we have to plug these values into the formula to solve for the height.

Answers

The question is worded weirdly, but the mean (average) is 3.3. The median is 4. The median would probably represent this better.

Step-by-step explanation:

The median is found by adding all of the numbers in the data set and then dividing by how many numbers there are.

The median is the middle number, which you find by alternately crossing out the biggest and smallest numbers.

Answer:

72 square feet

Step-by-step explanation:

Since you already know the 2 inches, you just need to find out the other side, and by subtracting the longer side 6 inches, to the shorter side on the furthest side 5 inches, you get 1 inch. And since each inch represents 6 feet, the final equation would be 12 (2x6) x 6 (1x6). So the answer would be 72 square feet.
