solve for x in this triangle
Answers
Answer:
x = 5.006 (approximate answer)
Step-by-step explanation:
According to the instructions, the two triangles are similar. Thus, we can write and solve an equation of ratios:
2x - 10 39
-------------- = ------------
78 169
x - 5 1
This reduces to ------------ = -----------
1 169
or (after cross-multiplication) 169x - 845 = 1
Solve for x: Add 845 to both sides, which results in 169x = 846
Dividing both sides by 169 results in x = 5.006 (approximate answer)

f(x) = x2 + 2x + 1, find f(x + h) and simplify.
Answers
Given:
The function is
[tex]f(x)=x^2+2x+1[/tex]
To find:
The value of [tex]f(x+h)[/tex] in simplified form.
Solution:
We have,
[tex]f(x)=x^2+2x+1[/tex]
Putting [tex]x=x+h[/tex], we get
[tex]f(x+h)=(x+h)^2+2(x+h)+1[/tex]
[tex]f(x+h)=x^2+2xh+h^2+2x+2h+1[/tex]
[tex]f(x+h)=x^2+h^2+2xh+2x+2h+1[/tex]
Therefore, the simplified value of [tex]f(x+h)[/tex] is [tex]x^2+h^2+2xh+2x+2h+1[/tex].

I need help! ABCD is a rectangle.
m<1 =
m<6 =
m<3 =
Answers
Answer:
m∠1 = 24°
m∠3 = 66°
m∠6 = 66°
Step-by-step explanation:
They are all near the corners of the rectangle
The corners always equal 90°
But as you can see, they are split down the middle by the X in the rectangle and we have only one angle to go off of; 24°
Since m∠1 is in the same triangle as that angle, and it looks exactly the same, the angle is exactly the same.
m∠3 and m∠6, if you look closely, are also the same. And as I said before, the corners always are 90°. Since 24° is taken from the neighboring triangle, the amount left is 66°, and remember, 24° + x° HAS to equal EXACTLY 90°. So
90 - 24 = 66
So both m∠3 and m∠6 = 66°

seventy percent of the fish in an aquarium are salmon. if there are a total of 450 fish in the aquarium, how many salmon are there? how many fish are not salmon
Answers
Answer:
There are 315 salmon and 135 fish that aren't salmon.
Step-by-step explanation:
The number of salmon in the aquarium would be 70% of the 450 fish, so to find the number you multiply .7 by 450:
450 × .7 = 315
So, there are 315 salmon. To find how many fish are not salmon, you would subtract 315 from 450:
450 - 315 = 135
So, 135 of the fish are not salmon.
If Nick's Flemish giant rabbit weighs 12 more pounds than his Holland lop rabbit, how much does his Flemish giant rabbit weigh?
Answers
Answer:

To fill a tank, 25 buckets of water is required. How many buckets of water will be required to fill the same tank if the capacity of the bucket is reduced to two-fifth of its present?
Answers
Answer:
10
One tank is 25 buckets of water, so 2/5 of a tank is 10 buckets of water.
Answer:
62.5
Step-by-step explanation:
Let the capacity of 1 bucket = x.
Then, the capacity of tank = 25x.
New capacity of bucket = 2x/5
Required number of buckets = 25x / (2x/5)
= 25x * 5/2x
= 125/2 = 62.5

this means angle
Answers
Answer:
∠9 + ∠10 = 135° combined, they are alternate equal to ∠2
∠1 =45° it is supplementary to ∠2
∠6 = 45° it is corresponding congruent to ∠8 which is alternate
equal to ∠1
∠4 + ∠5 = 135° combined, they are corresponding congruent to ∠2
The measure of the angles ∠1, ∠6, ∠4, ∠5, ∠9, and ∠10 will be 45°, 45°, 45°, 90°, 45°, and 90°, respectively.
What is an angle?The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360 °.
Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.
Corresponding angle - If two lines are parallel then the third line. The corresponding angles are equal angles.
Vertically opposite angle - When two lines intersect, then their opposite angles are equal.
Complementary angle - Two angles are said to be complementary angles if their sum is 90 degrees.
All the angles are mentioned on the diagram.
The measure of the angles ∠1, ∠6, ∠4, ∠5, ∠9, and ∠10 will be 45°, 45°, 45°, 90°, 45°, and 90°, respectively.
