Before we begin, I just want to remind you to not automatically assume that this is an equilateral triangle and that all of its three angles are equivalent, therefore meaning that C = 180 / 3 = 60°. Please DO NOT do this as it is incorrect and especially not possible in this problem as the angles are not equivalent.

If there is no clear indication such as dashes in the diagram or a statement specifying that it is an equilateral triangle, DO NOT assume that it is an equilateral triangle.

Now let's move on to solving the problem.

STEP-BY-STEP SOLUTION:

First let's establish the following formula:

Angle sum of a triangle = 180°

Therefore:

4x + 2x + 3x = 180°

Using the above equation, we will first make ( x ) the subject and solve accordingly as displayed below:

4x + 2x + 3x = 180°

9x = 180

x = 180 / 9

x = 20°

From this, we will substitue the value of x into the equation for C as displayed below:

C = 3x

C = 3 ( 20 )

C = 60°

Therefore, the answer is:

Option B - 60°

The average annual salary of the employees of a company in the year 2005 was ninety thousand dollars. It increased by the same f
4vir4ik [10]
Given:
year 0 - 2005 : 90,000
year 1 - 2006 : 91,200

91,200 - 90,000 = 1,200
1,200 / 90,000 = 0.013

90,000 (1+0.013)^1 ⇒ 90,000 (1.013)^1 =  91,170 OR 91,200

The best representation of the relationship between x and f(x) is choice 2.
f(x) = 90(1.013)x

Match each term with the appropriate example
brilliants [131]

Answer:

1.   Absolute value :  d.  | - 7| = 7

2.  All real numbers :  b.  3x = 3x

3.  x = -5  : c.  5x = -25

4.  No solution : a.  |2x| = -10

5.  Adding the opposite to both sides of the equation. : e.  Canceling

Step-by-step explanation:

1.   Absolute value :  d.  | - 7| = 7

The absolute value is considered the distance to 0... so if there's a negative sign in the value, the negative sign disappears.

2.  All real numbers :  b.  3x = 3x

If we divide both sides by 3, we have x = x, which will always be true.

3.  x = -5  : c.  5x = -25

If we multiply each side by 5, we have 5(x) = 5(-5) thus 5x = -25

4.  No solution : a.  |2x| = -10

The result of an absolute value cannot be a negative number.  So, that has no solution since there's no value of x that would make this true.

5.  Adding the opposite to both sides of the equation. : e.  Canceling

If you have for example (x = -5) and you add 5 on both sides, you cancel the value on the right side... (becomes x + 5 = 0).
