Answer:

Kindly check explanation

Step-by-step explanation:

Given that:

Sound quality test = every fifth siren

Mechanical quality = every 8th siren

Daily output = 350 siren

Percentage tested for mechanical quality :

Number of siren tested for mechanical quality / total output

Number of siren tested for mechanical quality = (350 / 8) = 43. 75

= 43 sirens

% tested for mechanical quality :

(43 / 350) * 100%

0.12285 × 100%

= 12.29%

What percent is tested for both types of quality at the same time?

Number tested for both types simultaneously = 8

% tested for both types of quality :

(8 / 350) * 100%

0.0228571 × 100%

= 2.28571%

= 2.29%

What is the value of X?
bearhunter [10]
Let's solve this problem step-by-step.

STEP-BY-STEP SOLUTION:

Let's first establish that the shape is a triangle meaning that the following formula is applicable as displayed below:

Angle sum of a triangle = 180°

As well as this, the shape is an equilateral triangle meaning that each angle of the triangle is equivalent in value. Also, the following formula is also applicable as displayed below:

Each angle of an equilateral triangle = the same value

Therefore:

Each angle of an equilateral triangle = angle sum of a triangle ÷ no. of angles in a triangle = 180° ÷ 3 = 60°

Based on this, the following is applicable:

2x - 4 = 60°

2x = 60 + 4

2x = 64

x = 64 / 2

x = 32°

ANSWER:

Therefore, the answer is:

The value of ( x ) is 32°
