Answer:
x = 14
Step-by-step explanation:
(5x - 19)° and (9x + 3)° are the measures of the interior angles on the same side of the transversal.
Therefore,
(5x - 19)° + (9x + 3)° = 180°
(5x - 19 + 9x + 3)° = 180°
(14x - 16)° = 180°
14x - 16 = 180
14x = 180 + 16
14x = 196
x = 196/14
x = 14
C) (3, 1.5) because the two lines intersect to one point and that's the answer
Answer:
Domain
Step-by-step explanation:
We are given the definition of sequence.
A sequence is a function whose domain is a set of natural numbers or a subset of natural numbers. We usually use the symbol 
to represent a sequence, where n is a natural number and is the value of the function on n.
(D) 80°, 140°, and 70° group of segments cannot form a triangle.

What is a triangle?</h3>
- A triangle is a three-edged polygon with three vertices.
- It is a fundamental shape in geometry.
- Triangle ABC represents a triangle with vertices A, B, and C.
- In Euclidean geometry, any three non-collinear points define a unique triangle and, by extension, a unique plane.
- In other words, the triangle is contained in just one plane, and every triangle is contained in some plane.
- There is just one plane and all triangles are enclosed in it if the entire geometry is merely the Euclidean plane; but, in higher-dimensional Euclidean spaces, this is no longer true.
To find which group of segments cannot form a triangle:
- 80°, 140°, and 70° cannot form a triangle because the sum of the three angles is 290°, whereas the sum of the angles in a triangle is 180°.
Therefore, (D) 80°, 140°, and 70° group of segments cannot form a triangle.

Answer:
7) BC = 10
8) BD = 20
Step-by-step explanation:
7) The segment addition theorem tells you ...
AB +BC +CD = AD
(3x+2) +(2x+4) +(3x-2) = 28
8x +4 = 28 . . . . collect terms
8x = 24 . . . . . . . subtract 4
x = 3 . . . . . . . . . divide by 8
BC = 2x+4 = 2(3) +4
BC = 10
__
8) AB +BD = AC +CD
(2x -14) +(-7 +3x) = (2x -3) +(9)
5x -21 = 2x +6
3x = 27
x = 9
BD = -7 +3x = -7 +3(9)
BD = 20
