Answer:

x = -12

Step-by-step explanation:

Let's solve your equation step-by-step.

8+x=−4

Step 1: Simplify both sides of the equation.

x+8=−4

Step 2: Subtract 8 from both sides.

x+8−8=−4−8

x=−12

Answer:

Step-by-step explanation:

1). In ΔTPW and ΔGHD,

Triangles will be congruent by the properties of congruence,

1). SSS - (Sides - Side - Side) property of congruence

2). SAS - (Side - Angle - Side) property of congruence

3). ASA - (Angle - Side - Angle) property of congruence

2). ΔABE ≅ ΔMNP

∠A ≅ ∠M

∠B ≅ ∠N

∠E ≅ ∠P

Side AB ≅ Side MN

Side AE ≅ Side MP

Side BE ≅ Side NP

Another way to write the congruency statement → ΔAEB ≅ ΔMPN

3). ΔQRY ≅ ΔJLS

∠Q ≅ ∠J

∠R ≅ ∠L

∠Y ≅ ∠S

Side QR ≅ Side JL

Side RY ≅ Side LS

Side QY ≅ Side JS

Anthe way to write the congruency statement → ΔQYR ≅ ΔJSL

Find the hypotenuse of each isosceles right triangle when the legs are of the given measure.

jasenka [17]

leg^2 + leg^2 = hyp^2

3√2 + 3√2 = hyp^2

4.24264068712 + 4.24264068712 = hyp^2

8.48528137424 = hyp^2

2.91295063024 = hyp

Hope this helps! ;)

<h3>Answer: x = 25</h3>

===================================================

Work Shown:

We'll use the pythagorean theorem

a^2 + b^2 = c^2

7^2 + 24^2 = x^2

49 + 576 = x^2

625 = x^2

x^2 = 625

x = sqrt(625)

x = 25

The hypotenuse is 25 units long.

Note: the value of c is always the hypotenuse, while the order of 'a' and b doesn't matter.

St lies on the coordinate plane with s located at (3.2). The midpoint of dt is z(3,9) state the location of the endpoint T thank

77julia77 [94]

Answer:

T = (3,16)

Step-by-step explanation:

The midpoint formula is just another version of the pythagorean theorem, and it states that the midpoint between (x1,y1) and (x2,y2) is $\left(\frac{x_1+x_2}{2}\right),\:\left(\frac{y_1+y_2}{2}\right)$

Substituting what we know:

endpoint S is (3,2) and endpoint T is (x2,y2)

Midpoint Z is (3,9). We will apply the formula -- backwards.

$\left(\frac{3+x_2}{2}\right)=3$ , solving with algebra we get x2 = 3

So the x-coordinate of endpoint T is 3.

$\left(\frac{2+y_2}{2}\right)=9\quad$ , solving with algebra, we get y2 = 16.

So the y-coordinate of endpoint T is 16.

So the location of endpoint T is (3,16)
