Find the value for x​
d1i1m1o1n [39]

Answer:

Value of x --> 15°

<u>Step-by-step explanation:</u>

(2x + 60°) and 6x lie on a straight line. So, they form a linear pair. Their sum gives 180°.

---> (2x + 60°) + 6x = 180°

     2x + 60° + 6x = 180°

     8x + 60° = 180°

     8x = 180°- 60°

     8x = 120

      x = \frac{120}{8}

<h3><u>x equals 15°</u></h3>

This above implies that:

  • The triangles can be mapped onto each other by rigid transformations such as reflection, translation and rotation
  • The transformation does not include dilation
  • Corresponding sides are congruent

The above means that the possible true statements are: (a), (d) and (e)

aleksklad [387]

Answer:

y = x [1-\frac{15}{100}]

Step-by-step explanation:

If the variable x represents the employee's pay before tax-exempt expenses and taxes are removed and y variable represents the employee's take-home pay after these deductions and if fifteen percent of an employee's taxable income is collected each paycheck, then y is given by

y = x [1-\frac{15}{100}]. (Answer)

For, example, an employee's payment is deducted by $350 at the rate of 15% tax and other deduction.

Therefore, \frac{15x}{100}=350, ⇒ x = $2333.33 is the before tax income of the person.
