100 POINTS PLEASE HELP!!
andrew-mc [135]

Answer:

a)  ∠2 and ∠4 are a linear pair

∠4 = 115°

b)  ∠2 and ∠7 are alternate exterior angles

∠7 = 65°

c) ∠2 and ∠3 are vertical angles

∠3 = 65°

Step-by-step explanation:

Linear pair : a pair of adjacent angles formed when two lines intersect. The two angles of a linear pair are always supplementary (two angles whose measures add up to 180°)

Alternate exterior angles : when two parallel lines are cut by a transversal (a line that intersects two or more other, often parallel, lines), the resulting alternate exterior angles are <u>congruent</u>.

Vertical angles : a pair of opposite angles formed by intersecting lines. Vertical angles are always <u>congruent.</u>

a)  ∠2 and ∠4 are a linear pair

⇒ ∠2 +∠4 = 180

⇒ 65 + ∠4 = 180

⇒ ∠4 = 180 - 65

⇒ ∠4 = 115°

b)  ∠2 and ∠7 are alternate exterior angles

⇒ ∠2 ≅ ∠7

⇒ ∠7 = 65°

c) ∠2 and ∠3 are vertical angles

⇒ ∠2 ≅ ∠3

⇒ ∠3 = 65°

The midpoint of AB is M (2, -1). If the coordinates of A are (1, 6), what are the
MatroZZZ [7]

The coordinates of B are (3, -8). Where the line-segment AB has the midpoint at M with coordinates (2, -1).

<h3>How to calculate the midpoint?</h3>

The midpoint on a line segment with two endpoints (x1, y1) and (x2, y2) is

Midpoint (x, y) = (\frac{x1+x2}{2}, \frac{y1+y2}{2})

<h3>Calculation:</h3>

The given line segment is AB with coordinates A(1, 6) and B(x2, y2).

M is the midpoint of line segment AB. Its coordinates are M(2, -1)

Then, the coordinates of B are calculated by

M(x, y) = (\frac{x1+x2}{2}, \frac{y1+y2}{2})

(2, -1) = (\frac{1+x2}{2}, \frac{6+y2}{2})

In comparing both sides,

2 = (1 + x2)/2 and -1 = (6 + y2)/2

On simplifying,

2 = (1 + x2)/2

⇒ 4 = (1 + x2)

⇒ 1 + x2 = 4

⇒ x2 = 4 - 1

∴ x2 = 3

-1 = (6 + y2)/2

⇒ 6 + y2 = -2

⇒ y2 = -2 - 6

∴ y2 = -8

Thus, the coordinates of the required point are B(3, -8).
