What are Parallel Lines Cut by Transversal?
Straight, equally spaced lines that never cross each other and are on the same plane are called parallel lines. The angles that are created when any two parallel lines are intersected by a line (referred to as the transversal) have a relationship. Corresponding angles, Alternate Interior Angles, Alternate Exterior Angles, and Consecutive Interior Angles are some of the several pairs of angles that are created at this intersection.
Corresponding angles
When two parallel lines are intersected by a transversal, the corresponding angles have the same relative position
Alternate Interior Angles
Alternate interior angles are formed on the inside of two parallel lines which are intersected by a transversal.
Alternate Exterior Angles
The pairs of angles formed on either side of a transversal that divides two parallel lines are known as alternate exterior angles.
Consecutive Interior Angles
When two parallel lines are cut by a transversal, the pairs of angles formed on the inside of one side of the transversal are called consecutive interior angles or co-interior angles.
Given data ,
Let the angle be ∠ABC = ( 3x - 70 )°
Now , from the figure ,
The value of angle ∠A = x°
The value of x° is equal to ( 3x - 70 )° because they are corresponding angles
Now , from the theorem of angles cut by transversal , we get
The pairs of angles formed on the same side of the transversal that are either both obtuse or both acute and are called corresponding angles and are equal in size
Each pair of corresponding angles on the same side of the intersecting transversal are equal to each other
So ,
Substituting the values in the equation , we get
x° is equal to ( 3x - 70 )°
x° = ( 3x - 70 )°
x = 3x - 70
Adding 70 on both sides of the equation , we get
3x = x + 70
Subtracting x on both sides of the equation , we get
2x = 70
Divide by 2 on both sides of the equation , we get
x = 35°
So , the value of ∠ABC = ( 3x - 70 )°
∠ABC = ( 3x - 70 )°
∠ABC = ( 135 - 70 )°
∠ABC = 35°
Hence , The value of the angle ∠ABC = 35°

The perimeter of a rectangle is 150. The length of the rectangle is 9 more than the width. Find the width.
Answers
Answer:
33
Step-by-step explanation:
Length = Width + 9
Perimeter = Length + Length + Width + Width
Perimeter = Width + 9 + Width + 9 + Width + Width = 150
4(Width) + 18 = 150
Subtract 18 from both sides:
4(Width) + 18 - 18 = 150 - 18
4(Width) = 132
Divide 4 on both sides:
[tex]\frac{4(Width)}{4} =\frac{132}{4}[/tex]

Note that the entire segment (JK) is the sum of the segments JI and IK. In other words:
[tex]JK=JI+IK[/tex]
We know that JK is (2x-1), JI is (2), and IK is (x+3). Substitute:
[tex]2x-1=(2)+(x+3)[/tex]
On the right, add:
[tex]2x-1=x+5[/tex]
Add 1 to both sides:

Subtract x from both sides. The right cancels:
[tex]x=6[/tex]
And the value of x is 6.

Ronald rents a car from Cheap Rent-a-Car for $25 plus $0.05 per mile. Dixon rents a car
from Great Cars for S40 plus $0.03 per mile. How many miles must they both drive for
their rental fees to be the same?
Answers
Answer:
750 miles
Step-by-step explanation:
Ronald
Rental fee = fixed cost + variable cost
= $25 + $0.05x
Where x = number of miles
Dixon
Rental fee = fixed cost + variable cost
= $40 + $0.03x
How many miles must they both drive for their rental fees to be the same?
Equate the two equations
$25 + $0.05x = $40 + $0.03x
Collect like terms
0.05x - 0.03x = 40 - 25
0.02x = 15
Divide both sides by 0.02
x = 15 / 0.02
= 750 miles
