Answer:
Side a = 23 Side b = 28 Side c =46
Step-by-step explanation:
First set up your equation witch is x-5+x+x-5*2=69
Then Simplify x+-5+x+x+-10=69
Then combine like terms 3x-15=69
Add 15 to both sides
After you will get 3x=84
then divide both sides by 3
You will get x=28
Then go back to your question it says THE FIRST IS 5 CM SHORTER THAN THE SECOND SIDE. THE THIRD SIDE IS TWICE AS LONG AS THE FIRST SIDE. So that tells you that to find A, you do 28-5=23, to side b is x so its 28, and to find side c you do 28-5*2=46. So A=23, B=28, and C=46.
no idea if this is what you're looking for but if it is then here's the answer:
Part 1) The mean is 151
Part 2) The mean absolute deviation is 9.1
Step-by-step explanation:
step 1
Find the mean
Sum all the values and divide by the number of values
step 2
Determine the absolute value of subtract the mean from each value
step 3
Find the mean of those distances
----> this number is called the mean absolute deviation (MAD)V
In tue picture, we can see 2 triangles and they already labeled 2 congruent sides. We also see that the line in the middle is being shared between the 2 triangles, making the side equal. Using the SSS theorem, we can prove that these teiangles are congruent to each other. Hope this helps.
Your answer would be 19 and 20.
To solve this, you need to first think about perfect square numbers, and which ones are the closest to 375. This is because perfect squares will always get square rooted back to a whole number, so therefore the ones around 375 would be the closest whole numbers.
Now, 400 is one of the easier to remember square numbers. It is 20 squared. 375 is pretty close to 400, however its slightly lower. So now, let's look at the closest perfect square that's less than 400: 19^2, or 361.
375 is between 361 and 400, so therefore it is between the square root of 361 and 400, or 19 and 20.
Good luck!
