This exercise is about a proof in Euclidian geometry. See the explanation below.

<h3>What is Euclidian Geometry?</h3>

The study of solid and flat objects using the axioms and theorems developed by the Greek mathematician Euclid is known as Euclidean geometry (c. 300 bce).

<h3>What is the statement that completes the above proof?</h3>

Given that S is the midpoint of \overline{QT}:

Hence QS = TS ......................1

It is right to indicate that

PQ = TV  ........................2

And ∠RSQ is vertically opposite to ∠TSV

Hence

∠RSQ = ∠TSV.........................3

Given 1, 2, and 3,

Δ QRS ≅ ΔVTS

Therefore,

Δ QRS ≅ ΔVTS

and ∠ RSQ can be termed to be congruent to ∠TSV.

<h3>What does it mean for an angel to be congruent?</h3>

It is to be noted that the measure of an angle is the same for congruent angles. An ordinary pentagon, for instance, has five sides and five angles, each of which is 108 degrees.

The angles of a regular polygon will always be congruent, regardless of its size or scale.

Breta worked to solve a system of equations 4x +y=-5 x-y=-5
Sever21 [200]

Answer:

x=-2, y=3. (-2, 3).

Step-by-step explanation:

4x+y=-5

x-y=-5

------------

x=y+(-5)

x=y-5

substitute into the first equation,

4(y-5)+y=-5

4y-20+y=-5

5y-20=-5

5y=-5+20

5y=15

y=15/5=3

x=3-5=-2

melamori03 [73]

Answer:

a person travel 50 ft from the bottom to the top of the escalator

Step-by-step explanation:

An escalator lifts people to the second floor of a building, 25 ft above the first floor. The escalator rises at a 30 degree angle

The escalator forms a right angle triangle

opposite to 30 degree angle is 25 feet. to find the distance from the bottom to the top of the escalator we find the hypotenuse

let x be the hypotenuse

sin(theta)=\frac{opposite}{hypotenuse}

sin(30)=\frac{25}{x}\\x sin(30)= 25\\x=\frac{25}{sin(30)} \\x=50\\

a person travel 50 ft from the bottom to the top of the escalator

Hard question posted the picture of the problem
Softa [21]

Q(2a , 0)

R (2b, 2c)

Midpoint QR

x = (2a + 2b)/2

= 2(a+b) / 2

= a + b

y = (0+ 2c)/2

= 2c/ 2

= c

Midpoint QR (a + b, c)

Answer: third option

(a + b, c)

Find the value of x. Please help.!!<br> Need to show work.
EastWind [94]

Answer:

(x-54)° + 2x° + 99° = 360

=> x + 2x + 99 – 54 = 360

=> 3x + 45 = 360

=> 3x = 360 – 45

=> x = 315/3

=> x = 105

The value of x is 105
