PLS HELPPYTHAGOREAN THEOREM

Answers

Answer 1
A^2+B^2=C^2 or the length of the 2 shortest sides squared equals the longest leg squared
Answer 2

Answer:

  8.  20.8 units

  9.  isosceles

Step-by-step explanation:

8.

The vertical altitude line divides the triangle into two congruent right triangles. Each has a horizontal leg of 4 units, and a vertical leg of 5 units. (You can find these lengths by subtracting coordinates, or by counting grid squares.)

slant sides

The hpotenuses of these right triangles are the short sides (PR, QR) of the larger triangle PQR. We can find their length using the Pythagorean theorem. Defining S as point (-2, -1), we have ...

  PS² +SR² = PR² . . . . . . . . . . . . the Pythagorean theorem relation

  4² +5² = PR² = 16 +25 = 41 . . . with numbers filled in

  PR = √41 . . . . . . . . . . . . . . take the square root

  PR ≈ 6.4 . . . . . . . . . . . round to tenths

horizontal side

The length of side PQ is 8 units, found by subtracting x coordinates ((2 -(-6)) = 8), by counting grid squares, or by doubling the length of PS (2(4) = 8).

perimeter

The perimeter of the triangle is the sum of its side lengths:

  perimter = PR +QR +PQ = 6.4 +6.4 +8 = 20.8

The perimter of triangle PQR is 20.8 units.

__

9.

Sides PR and QR are congruent, so the triangle is isosceles.

_____

Additional comment

A triangle whose vertices are integer grid coordinates cannot be equilateral.

Consider the figure.
Find the area of the composite figure to the nearest half unit. Use 3.14 for π

Answers

Answer:

23.5 cm^2

Step-by-step explanation:

First calculate the "rectangle" with the half-circle filled in

9*3 = 27

Then calculate the half-circle using the formula for the area of a circle [tex]\pi r^{2}[/tex], then dividing it by half

3.14 * 1.5 * 1.5 / 2 = 3.5325

Subtract the area of the half-circle from the area of the rectangle

27-3.5325

= 23.4675

= 23.5 (cor. to the nearest half unit)

The answer is 23.5 cm squared

1/10x+9/10=1/10(BLANK)

Answers

Answer:

x=-8

Step-by-step explanation:

1 Simplify 1/10x to x/10.

x/10 + 9/10 = 1/10

2 Join the denominators.

x+9/10 = 1/10

3 Multiply both sides by 10.

x+9 = 1/10×10

4 Cancel 10.

x+9=1

5 Subtract 9 from both sides.

x=1-9

6 Simplify  1-9 to  -8.

x=-8

Solve the following systems using the elimination method.

Step-by-step explanation:

[tex]$$Solve the following system: \\$\left\{\begin{array}{ll}7 y+4 x=19 & \text { (equation 1) } \\ -y+2 x=-13\end{array} \quad\right.$ (equation 2)\\\\Subtract $\frac{1}{2} \times($ equation 1) from equation 2 :\\$\left\{\begin{array}{l}4 x+7 y=19 \ \ \ \ (\text{equation 1}) \\ 0 x-\frac{9 y}{2}=-\frac{45}{2}\end{array}\right.$ (equation 2)\\\\Multiply equation 2 by $-\frac{2}{9}$ :\\[/tex]

Answer: x = -4, y = 5

Step-by-Step Explanation:

=> 4x + 7y = 19 (Eq. 1)
=> 2x - y = -13 (Eq. 2)

We can multiply Eq. 2 by 7 in order to make the coefficients of ‘y’ same in both the equations thus being able to eliminate ‘y’ and find ‘x’

Therefore,
(2x - y = -13) * 7
=> 14x - 7y = -91 (Eq. 3)

On Adding Eq. 1 and 3, we get :-

18x = -72 (‘y’ gets Eliminated)
x = -72/18
=> x = -4

Therefore, x = -4

Substitute value of ‘x’ in Eq. 2 :-

2x - y = -13
2(-4) - y = -13
-8 - y = -13
-y = -13 + 8
-y = -5
=> y = 5

Therefore, y = 5
