When we add the angle that has x° and the angle that has (4x-20)° we need to get 180°.

Mathematically: x° + (4x-20)° = 180°.

We solve for x:

x°+4x°-20°=180°, we put all numbers that we know on the right side and all unknowns on the left side:

5x°=200°, we divide by 5 and get:

x=40°

So the correct answer is D. x=40°.

Answer:

The division was computed incorrectly.

Step-by-step explanation:

Given

Workings:

$\frac{5}{8}$ to percentage

$\frac{8}{5} = 1.6 = 160\%$

Required

Explain his error

The question says 5/8

Instead, Alejandro's working shows 8/5.

This working is done in an incorrect order and the correct solution is:

Let

$x = \frac{5}{8}$

Solve the fraction

$x = 0.625$

Multiply by 100%

$x = 0.625 * 100\%$

$x = 62.5\%$

<em>Hence, option (a) is correct.</em>

Answer:

x=±√35

Step-by-step explanation:

Take the square root of both sides of the equation to eliminate the exponent on the left side.

x=±√35

The complete solution is the result of both the positive and negative portions of the solution.
