What is the value of X?

Mathematics
1 answer:
natali 33 [55]3 years ago
8 0

Answer: x=8

Step-by-step explanation: Since we know that segment AB and BC are the same measure indicated by the black lines running perpendicular to the lines in triangle themselves, we know that angle A and angle C are the same measure. This means we know this equation... Solve this to complete step 1...

69°=(9y-3)°

If you solve for y, you should get 8. This means that y=8. In knowing that a triangle's interior angles add up to 180°, we know that Angle B must be... Solve this equation for step 2...

∠B=180°-(∠A+∠C)

If you solve to find angle B, you should get that ∠B=42°. Knowing this, we can set up another equation similar to that in step 1 (when we found y knowing the angle) to find x... Solve this equation for your third and final step...  

42°=(5x+2)°

If done step 1 through 3 correctly, you should get x to be equal to... and the final answer... x=8

Help me pls ☹️☹️☹️☹️​
zheka24 [161]

The slope of a line can be found by graph using rise over run (\frac{rise}{run}). Look at the image below to see what this mean.

Rise = vertical

run = horizontal

I took two clear points on the line as seen below and drew a right angle that formed a right triangle with the line.

Now let's count how many units the rise is (look at the second image). This is 3 units

rise = 3

Count the units of the run (third image). This is 1 unit

run = 1

Let's put these two numbers together in the \frac{rise}{run} form:

\frac{3}{1} or simplified = 3

However, this is not the final answer. This is a negative slope, meaning that when you look at the line from left to right (like when you are reading words) the line reaches from the top left corner to the bottom right corner. A positive slope (reading left to right) reaches from the bottom left corner to top right corner.

To signify that the slope is negative you simply add a negative sign to it:

-3

Let me know if you have any further questions.

A number is written with the following factorization:2² x 3 x 5⁴ x 8 x 11².Is this factorization a prime factorization? Explain
BigorU [14]

Answer:

NO, this is not prime factorization.

The correct prime factorization is = 2^{5} X 3 X 5^{4} X 11^{2}

Step-by-step explanation:

Prime factorization means, writing the given number as product of prime numbers.

In the above case, in the prime factorization,<em> the number 8 is present which is not a prime number.</em>

8 can be further represented as product of prime numbers as,

8 = 2^{3}

Now the prime factorization reduces to,

= 2^{2} X 3 X 5^{4} X 2^{3} X 11^{2}

= 2^{5} X 3 X 5^{4} X 11^{2}
