Given:
Vertices of a square are A(-4,6), B(5,6) C(4,-2), and D(-5,-2).
To find:
The intersection of the diagonals of square ABCD.
Solution:
We know that diagonals of a square always bisect each other. It means intersection of the diagonals of square is the midpoint of diagonals.
In the square ABCD, AC and BD are two diagonals. So, intersection of the diagonals is the midpoint of both AC and BD.
We can find midpoint of either AC or BD because both will result the same.
Midpoint of A(-4,6) and C(4,-2) is
[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]
[tex]Midpoint=\left(\dfrac{-4+4}{2},\dfrac{6+(-2)}{2}\right)[/tex]
[tex]Midpoint=\left(\dfrac{0}{2},\dfrac{6-2}{2}\right)[/tex]
[tex]Midpoint=\left(\dfrac{0}{2},\dfrac{4}{2}\right)[/tex]
[tex]Midpoint=\left(0,2\right)[/tex]
Therefore, the intersection of the diagonals of square ABCD is (0,2).
When Jose woke up the temperature was 74°. It
reached a high temperature of 91°. What was
the percent of increase of these temperatures?
Answer:
22.97
Step-by-step explanation:
Given that,
Initial temperature = 74°
After some time, the new temperature = 91°
We need to find the percent increase in the temperature.
The formula for the percentage increase is given by :
[tex]\%=\dfrac{|\text{final value-initial value}|}{\text{initial value}}\times 100\\\\=\dfrac{91-74}{74}\times100\\\\=22.97\%[/tex]
So, the increase in temperature is 22.97%.

ANSER FOR REAL OR BANHAMMER WILL BE IN YOUR FACE
Step-by-step explanation:
Since the square is folded along its diagonal,
Perimeter of each triangle
= 2 * Side of square + Diagonal of square.
Side of square
= √(Area of square)
= √(49in²) = 7in.
Diagonal of square
= √(2 * Area of square)
= √(98in²) = 7√2in.
Hence we have 2 * 7in + 7√2in = 7(2 + √2) in.

The 3 feet side and 4 feet side with a right angle between them. Then the 5 feet side will fit to form a right-angle triangle. Then the correct option is B.
What is a Pythagoras theorem?The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.
The Pythagoras theorem formula is given as
H² = P² + B²
Pythagorean theorem using side links chosen from 3 feet, 4 feet, 5 feet in 6 feet.
Then
5² = 3² + 4²

Answer:
1.) 5 2.) 10.58
Step-by-step explanation:
For each one, you use the equation a^2 + b^2 = c^2 where c is the "hypotenuse"-- the side of the triangle opposite (facing) the right angle which is shown with a small box. The variables a and b do not matter, as long as they are the "legs", the other 2 sides.
So it is 4^2 + 3^2 = c^2 which simplifies to 16+9=25=c^2 and square root both sides and you get c=5
and 12^2 + b^2 = 16^2 which simplifies to 144+ b^2 = 256 and subtract 144 from both sides and you get b^2 = 112 and square root both sides and it is approximately 10.6 :)

If triangle A B C is congruent to triangle D E F, the measure of angle A equals 55 degrees, and the measure of angle E equals 25 degrees, what is the measure of angle C?
A. 25°
B. 55°
C. 80°
D. 100°
Answer:
D. 100
Step-by-step explanation:
Answer:
100°
Step-by-step explanation:
Since ΔABC ≅ Δ DEF, and the sum of the measures of the interior angles of a triangle is 180°, subtract the given angle measurements from 180°.
∠A ≅ ∠D, ∠B ≅ ∠E, ∠C ≅ ∠F (The vertices are written in this order because they are corresponding angles.)
180° - 55° = 125° - 25° = 100°
∠C is 100°

A figure has been dilated from the origin by a scale factor of one seventh. if another dilation from the origin maps the dilated image back
onto the original figure, what is its scale factor?
Answer:
its scale factor is 3
Step-by-step explanation:
plz mark brainliest
To map the dilated image back onto the original figure, the scale factor needed is 7.
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.
Dilation is the increase or decrease in the size of a figure by a factor.
If a figure is dilated from the origin by a scale factor of one seventh, it is given by:
(x, y) ⇒ [(1/7)x, (1/7)y]
To map the dilated image back onto the original figure, the scale factor needed is 7. Hence:
[(1/7)x, (1/7)y] ⇒ (x, y)
