Answer:
5.7 unit
Step-by-step explanation:
From the question,
Applying pythagoras theorem,
a² = b²+c²....................... Equation 1
From the diagram.
a = /QX/, b = /XR/, c = /RQ/
Given: b = /XR/ = 4 units, c = /RQ/ = 4 units.
Substitute these values into equation 1
a² = 4²+4²
a² = 16+16
a² = 32
a = [tex]\sqrt{32}[/tex]
a = 5.7 units
Hence, QX = 5.7 units

c. Add the two equations
d. Multiply the second equation by 2

Step-by-step explanation:
Which of the following is a true statement about the angles in the figure below?
Answer:
The statement which is true about the angles in the figure is;
The measure of Angle 4 is 137 degrees
Step-by-step explanation:
From the question diagram, we have;
The interior angles of the triangle are;
43°, 56°, and ∠1
Therefore, by the angle sum theorem, we have;
∠1 = 180° - 43° - 56° = 81°
∠1 = 81°
The measure of ∠1 is 81°
By the sum of angles on a straight line, we have;
∠1 + ∠2 = 180°
∴ 81° + ∠2 = 180°
∠2 = 180° - 81° = 99°
The measure of ∠2 is 99°
Similarly, for the angles 56° and ∠3 which are on a straight line, we have;
56° + ∠3 = 180°
∠3 = 180° - 56° = 124°
The measure of ∠3 is 124°
For the angles 43° and ∠4 which are on a straight line, we have;
43° + ∠4 = 180°
∠4 = 180° - 43° = 137°
The measure of ∠4 is 137°
Therefore the true statement is the measure of angle 4 is 137 degrees.

1) Nine months ago Alexa deposited $7,000 in a three-year CD. She has received $224.16 in
interest. She withdraws $1,000. This is before the CD matures, so she pays a $250 penalty.
What is her balance after the withdrawal?
Answer:
the balance after the withdrawal is $5,974.16
Step-by-step explanation:
The computation of the balance after the withdrawal is shown below:
= Deposited amount + interest received - withdrawn amount - penalty charges
= $7,000 + $224.16 - $1,000 - $250
= $5,974.16
Hence, the balance after the withdrawal is $5,974.16

Write an equation of the line with a slope of −7 and y-intercept of 1.
Answer:
y = -7x + 1
Step-by-step explanation:
Remember the formula for slope-intercept form: y = mx+ b
m is equal to the slope value
b is equal to the y-intercept value
Meaning, when you substitute the values in, you get:
y = -7x + 1
Answer:
y = -7x - 1 is the desired equation.
Step-by-step explanation:
Choose the form of the equation of a straight line that requires the least amount of work. In this particular case we are given the slope (-7) and the y-intercept (1), and so use the slope-intercept form y = mx + b:
y = -7x - 1 is the desired equation.

Answer:
triangle abd is isosceles triangle and triangle dbc is equilateral triangle.
opposite sides of equal angles are same. so, ad= bd
and bd is the side of equilateral triangle. so, bd=bc=dc
perimeter of quadrilateral = sum of all sides.
perimeter=11+8+8+8
perimeter =35
The perimeter of the given quadrilateral is 35 units.
What is a quadrilateral?A polygon with four sides, four angles, and four vertices is called a quadrilateral. The Latin words Quadri, which means four, and latus, which means side, were combined to create the English word quadrilateral.
We know the perimeter of any planer figure is the sum of the lengths of all the sides.
We have ΔABD with side lengths 8 units and 11 units with two similar angles.
∴ The length opposite to the missing side will also be 8 units and hence
ΔBCD will also the side lengths of 8 units as it is an equilateral triangle.
∴ The perimeter of the quadrilateral is (11 + 8 + 8 + 8) units.
= 24 + 11 units.
= 35 units.

[tex] \underline{ \underline{ \text{QUESTION : }}}[/tex] In the given quadrilateral PQRS, the mid-points of the sides PQ , QR , RS and SP are A , B , C and D respectively. Prove that ABCD is a parallelogram.
Answer:
See Below.
Step-by-step explanation:
We are given that A, B, C, and D are the midpoints of sides PQ, QR, RS, and SP, respectively.
And we want to prove that ABCD is a parallelogram.
By the definition of midpoint, this means that:
[tex]SD\cong DP, \, PA\cong AQ, \, QB\congBR, \, \text{ and } RC\cong CS[/tex]
To prove, we can construct a segment from S to Q to form SQ. This is shown in the first diagram.
By the Midpoint Theorem:
[tex]DA\parallel SQ[/tex]
Similarly:
[tex]CB\parallel SQ[/tex]
By the transitive property for parallel lines:
[tex]DA\parallel CB[/tex]
Likewise, we can do the same for the other pair of sides. We will construct a segment from P to R to form PR. This is shown in the second diagram.
By the Midpoint Theorem:
[tex]AB\parallel PR[/tex]
Similarly:
[tex]DC\parallel PR[/tex]
So:
[tex]AB\parallel DC[/tex]
This yields:
[tex]DA\parallel CB\text{ and } DC\parallel AB[/tex]
By the definition of a parallelogram, it follows that:
[tex]ABCD\text{ is a parallelogram.}[/tex]

Answer:
The answer is 3p(7p+q)
Step-by-step explanation:
If we first take given values as an area of a rectangle, we get: 7p+q times 6p
If we construct the rectangle, we can see that the given triangle takes exactly half of the area of the rectangle, thus the area of a triangle is:
(7p+q times 6p)/2
6p(7p+q)/2=3p(7p+q)

HELPPP
Answer:
If he kept taking notes at the same pace, he would have 16 pages of notes in his notebook.
Step-by-step explanation:
By dividing the number of pages of notes taken by the time spent taking them, you can find his rate of note-taking, which is 4 pages an hour. By adding another hour of notes, he should have 16 pages of notes. But if this question is asking for 4 more hours, the answer would be 28 pages.
