What is the length of the altitude drawn to the hypotenuse? The figure is not drawn to scale. * 12 3 X W3 x 12 Z Y Your answer
Answer:
What is the length of the altitude drawn to the hypotenuse?, Corollary: The length of the altitude to the hypotenuse of a right triangle is the geometric mean of the lengths of the two segments of the hypotenuse.
Furthermore, When an altitude is drawn to the hypotenuse of a given right triangle the new figure comprises two similar right triangles?, Theorem 62: The altitude drawn to the hypotenuse of a right triangle creates two similar right triangles, each similar to the original right triangle and similar to each other. Figure 2 shows the three right triangles created in Figure . They have been drawn in such a way that corresponding parts are easily recognized.
Finally, When the altitude is drawn to the hypotenuse of a right triangle three similar triangles are formed?, The Inscribed Similar Triangles Theorem states that if an altitude is drawn from the right angle of any right triangle, then the two triangles formed are similar to the original triangle and all three triangles are similar to each other. Perpendicular lines are lines that intersect at a 90^{circ} angle.

Answer:
[tex]\red{ m\angle B= 121\degree}\\\\\purple{AD=23\: units}[/tex]
Step-by-step explanation:
Quadrilateral ABCD is a parallelogram.
opposite angles of a parallelogram are equal in measure.
[tex]\implies (10x-19)\degree=(9x-5)\degree[/tex]
[tex]\implies 10x-19=9x-5[/tex]
[tex]\implies 10x-9x=19-5[/tex]
[tex]\implies x=14[/tex]
[tex]m\angle B= (9x-5)\degree[/tex]
[tex]\implies m\angle B= (9*14-5)\degree[/tex]
[tex]\implies m\angle B= (126-5)\degree[/tex]
[tex]\huge\implies m\angle B= 121\degree[/tex]
Opposite sides of a parallelogram are equal.
3y - 1 = y + 15
3y - y = 15 + 1
2y = 16
y = 16/2
y = 8
AD = 3y - 1 = 3*8 - 1 = 24 - 1
AD = 23

Ms. Jacobi writes the equation x+y=z. If x = 5, y = 3, and z = 53,
is the equation true? Explain your reasoning.
Answer:
no
Step-by-step explanation:
Because if we substitute the value of x,y and z we get
x+y=z
5+3=53(FALSE)
Answer and Step-by-step explanation:
No, this equation is not true. But in order to show this, we need to write out the equation. So if x = 5, and y = 3, then the equation for this equation would look like this:
5 + 3 = 8.
That is incorrect because 5 + 3 does not equal 53. This is a trick question that is trying to trick you. Now if that 5 was a 50, then this equation would be true.
So, 5 + 3 ≠ 53.
I hope that this helps.
what does a(b-c) = to?
Solution:
The expression "a(b-c)" is an example of distributive property. To simplify it, simply multiply a by the terms inside the bracket.
Simplifying the distributive property.
=> a(b - c)=> (a x b) + (a x -c)=> ab - acHence, the simplified expression is ab - ac.
We can use the distributive law to simplify it or factor it but more
[tex]\\ \tt\hookrightarrow a(b-c)[/tex]
[tex]\\ \tt\hookrightarrow a(b)-a(c)[/tex]
[tex]\\ \tt\hookrightarrow ab-ac[/tex]

There are 21 students in class. The median age of the students is 23. The oldest student is 29
Please explain
Answer:
At least one student is 23: Must be true
Some students are younger than 15: Could be true
Step-by-step explanation:
Statement 1: A median is a number in the middle for ex. 1, 2, 3, 4, 5 in this example 3 is the median. Another ex could be 1, 2, 3, 4, 5, 6. This time you would have to add (3 + 4), divide by 2, which equals 3.5.
Since there are 21 students in class making it an odd number 23 must be true.
Statement 2: Based on the information I am given, I would say could be true because the difference between the oldest and the median is 29 - 23 = 6 so it could be true.
Answer:
1) At least one (the 11th) student is 23 (years old), Must be true
2) Some students are younger than 15 Could be true
Step by step explanation:
1) The given parameters are;
The number of student in the class = 21
The median age of the student = 23
The age of the oldest student = 29
Therefore, given that the median age = The age of the (n + 1)/2 the student
Where;
n = The number of student in the class = 21
The median age = The age of the (21 + 1)/2 th = 11 th student, when the age of the students are arranged in increasing order, therefore, we have;
At least one (the 11th) student is 23 (years old), Must be true
2) Given that there are 10 students with ages equal to or lower than the median age, and the difference between the median age and the age of the oldest student = 29 - 23 = 6 years, we have;
Some students are younger than 15 Could be true
2 2/5 divided by 2 1/10
firstly let's convert the mixed fractions to improper fractions and then divide.
[tex]\stackrel{mixed}{2\frac{2}{5}}\implies \cfrac{2\cdot 5+2}{5}\implies \stackrel{improper}{\cfrac{12}{5}} ~\hfill \stackrel{mixed}{2\frac{1}{10}}\implies \cfrac{2\cdot 10+1}{10}\implies \stackrel{improper}{\cfrac{21}{10}} \\\\[-0.35em] ~\dotfill\\\\ \cfrac{12}{5}\div \cfrac{21}{10}\implies \cfrac{12}{5}\cdot \cfrac{10}{21}\implies \cfrac{120}{105}\implies \cfrac{8}{7}\implies 1\frac{1}{7}[/tex]
Answer:
first make them improper fractions
2 2/5 = 12/5
2 1/10 = 21/10
now set them up
12/5 divided by 21/10
make 21/10 a reciprocal(flip the fraction upside down) and multiply across
12/5 x 10/21 = 1.14 or 1 1/7
