Answer: x=7

               ab=21

               bc=14

Step-by-step explanation:

ab=3x

bc=2x±7

ac=42

3x±2x±7=42

5x±7=42

5x=42-7

5x=35

to get the value of x you divide 35 by 5x

35÷5x=7

so the value of x is 7

ab=3x

x=7

3x=7×3x

7×3=21

x=7

2x=7×2x

2×7=14

All the angles created by the transversal intersecting through a pair of parallel lines have got many names and connections with each other, like Alternate Angles, Corresponding angles, consecutive interior angles etc.

As per the question statement, We are given a pair of parallel lines which is cut by a transversal. We are supposed to mark the following angles.

Alternate Interior Angles, Alternate Exterior Angles, Corresponding Angles and Consecutive Interior Angles.

Here is an attached image of the same with angles marked on it.

Alternate Interior Angles: ∠3 = ∠5 and ∠4=∠6

Alternate Exterior Angles: ∠2=∠8 and ∠1=∠7

Corresponding Angles: ∠1=∠5 , ∠4=∠8 , ∠3=∠7 and ∠2=∠6

Consecutive Interior Angles: ∠4=∠5 and ∠3=∠6

  • Parallel Lines: Parallel lines are those straight lines that are, no matter how far they are extended, always the same distance apart from one another.
  • Transversal Line: In geometry, a transversal line intersects two lines in the same plane at two different locations.

Maxwell is taking out a loan for $8,750 for 2 years at an APR of 9.75%. What would be the finance charge to the nearest whole do
Sladkaya [172]

Answer:

Step-by-step explanation:

Using the formula for calculating simple interest

SI = principal × rate × time/100

Given

Principal = $8750

Rate = 9.75%

Time = 2years

Substitute

Interest = 8750×9.75×2/100

Interest = 87.59×19.5

Interest = 1,706.25

Hence the finance charge to the nearest whole dollar is $1706
