Answer:

Rectangle has two(2) lines of reflections

A square has four(4) lines of reflections

Step-by-step explanation:

Lines of reflection also known as lines of symmetry ,

In a rectangle there are two( 2) lines of symmetry and they are found along the midpoints of the opposite side of the rectangle, while for A square there are four (4) lines of reflections which can be seen along the midpoint of  the opposite sides of the square and also along the midpoint of the opposite vertices of the square.

The sum of the angles of a triangle is 180°. If one angle of a triangle measures x and the second angle measures (5x +19)º
lapo4ka [179]

Answer:

third angle = (-6x + 161)°

Step-by-step explanation:

180° = (x)° + (5x + 19)° + third angle →

180° = (6x + 19)° + third angle →

180° – (6x + 19)° = (6x + 19)° + third angle – (6x + 19)° →

180° – (6x + 19)° = third angle →

180° + -(6x + 19)° = third angle →

180° + (-6x)° + (-19)° = third angle

180° – 6x° – 19° = third angle

(180° – 19°) – 6x° = third angle

161° – 6x° = third angle

third angle = 161 – 6x°

third angle = -6x° + 161°

third angle = (-6x + 161)°

How many solutions does the following system of equations have y=5/2x+2 2y=5x+8
irakobra [83]

Answer:

No solutions.

Step-by-step explanation:

If you normalize the second one by dividing by 2, you get:

y = 5/2x+4.

Now you see that both have the same slope (5/2). They are parallel lines that never intersect.

Jane says that she can use addition to show that the graphs of 2x - 3y = 1 and 2x + 3y = 2 are intersecting lines. In two or mor
iogann1982 [59]
For this case we have the following equations:
 2x - 3y = 1
 2x + 3y = 2
 When adding both equations we observe that:
 Sentence 1: we have an equation of a variable, which in this case will be x. We can clear the value of x.
 Sentence 2: Knowing the value of x, we can substitute in any equation and find the value of y.
 Sentence 3: The value of x and y represents the point of intersection of both lines (x, y).

Anyone feel like helping me??

The angles of a triangle add up to 180 degrees

65 + 3x - 10 + 2x = 180
5x + 55 = 180
5x = 180 - 55
5x = 125
x = 125/5
x = 25 <====

m < B = 3x - 10 = 3(25) - 10 = 75 - 10 = 65 <== B is 65 degrees
m < C = 2x......= 2(25) = 50 <== C is 50
