Answer:

Step-by-step explanation:

This is classic right triangle trig. Side a, our unknown, is adjacent to angle C which is a given. You always have to use a given angle and side to find a missing side, so we have to figure out how the two givens are related to our unknown. Side a is adjacent to angle C, and we are also given the hypotenuse. We know side a is not the hypotenuse since the hypotenuse is ALWAYS the side across from the 90 degree angle. The tan ratio of angle C will give us a way to have only one unknown.

tan 43 = a/26 and

26 tan 43 = a

Use your calculator now to find the missing side.

a = 24.2 units long

stepan [7]

Answer:

The total number of employees are 79310 .

Step-by-step explanation:

Formula

$Percentage = \frac{Part\ value\times 100}{Total\ value}$

As given

An international company has 27,600 employees in one country. If this represents 34.8% of the company's employees .

Part value = 27600

Percentage = 34.8%

Putting all the values in the formula

$34.8 = \frac{27600\times 100}{Total\ value}$

$Total\ value = \frac{2760000}{34.8}$

Total value = 79310 (Approx)

Therefore the total number of employees are 79310 .
