Answers: Angle A is 36 degrees, angle C is 54 degrees
=================================================================
Work Shown:
The angles A and C are complementary, meaning they add to 90 degrees.
(Angle A) + (Angle C) = 90
(2x-4) + (2x+14) = 90
(2x+2x)+(-4+14) = 90
4x+10 = 90
4x+10-10 = 90-10 .... subtract 10 from both sides
4x = 80
4x/4 = 80/4 ..... divide both sides by 4
x = 20
If x = 20, then,
angle A = 2x-4 = 2*20-4 = 40-4 = 36 degrees
angle C = 2x+14 = 2*20+14 = 40+14 = 54 degrees
Note how A+C = 36+54 = 90 which helps confirm our answers.
Answer:
If the graph of a function f is known, it is easy to determine if the function is 1 -to- 1 . ... If no horizontal line intersects the graph of the function f in more than one point, then the function is 1 -to- 1 . A function f has an inverse f−1 (read f inverse) if and only if the function is 1 -to- 1 .

"Product" means we are looking at a multiplication problem.
Can be written as:
A number (n) times 50
n x 50
The simplest (and most common way) to write it:
50n
The measures of the angles are given as follows:
<h3>What is the value of x?</h3>
Angle ABD is the sum of angles BCD and ABC, hence:
ABD = BCD + ABC.
We replace the measures to find the value of x, hence:
6x - 9 + 4x - 1 = 82.
10x - 10 = 82.
10x = 92.
x = 9.2.
<h3>What are the measures of the angles?</h3>
With x, we can find the measures of the angles, as follows:
- ABC = 6(9.2) - 9 = 46.2º.
- CBD = 4(9.2) - 1 = 35.8º.

Answer:
The percent increase is 20%.
Step-by-step explanation:
It's fairly simple.
Multiply 10 by (100/10) which is 10 to get 100.
Multiply 12 by 10 to get 120.
120 - 100 = 20
