Answer:

6 sq. in

Step-by-step explanation:

To find area of triangle: base* height *1/2

height needs to be at a 90 degree angle from the base.

In this example, the base is 3 in, and the height is 4 in.

Plug these two into the equation

3 * 4 * 1/2 = 12 * 0.5 = 6

1/3(33x +15) - 1/3 ( 21x +18) =10

inn [45]

      ¹/₃(33x + 15) - ¹/₃(21x + 18) = 10
¹/₃(33x) + ¹/₃(15) - ¹/₃(21x) - ¹/₃(18) = 10
   11x + 5 - 7x - 6 = 10
   11x - 7x + 5 - 6 = 10
      4x - 1 = 10
      + 1   + 1
   4x = 11

In the interval 0 degrees < x < 360 degrees, find the values of x for which tan x = 2.7475. Give your answers to the neare

Answer:

<em>Thus, the values of x are 70° and 250°</em>

Step-by-step explanation:

<u>Trigonometric Functions</u>

The tangent is defined as:

$\displaystyle \tan\theta=\frac{\sin\theta}{\cos\theta}$

Given a value for the tangent, there are two angles with the same tangent, one of them being $\theta$ and the other $\theta$ +180°.

We are given:

$\tan x=2.7475$

The angle is the inverse tangent:

$x=arctan (2.7475)$

Using a scientific calculator, we find the first angle:

x=70°

The second angle is found adding 180°:

x=70°+180°=250°

Thus, the values of x are 70° and 250°
