Answer:

Simplifying

-38 = -0.4k

Solving

-38 = -0.4k

Solving for variable 'k'.

Move all terms containing k to the left, all other terms to the right.

Add '0.4k' to each side of the equation.

-38 + 0.4k = -0.4k + 0.4k

Combine like terms: -0.4k + 0.4k = 0.0

-38 + 0.4k = 0.0

Add '38' to each side of the equation.

-38 + 38 + 0.4k = 0.0 + 38

Combine like terms: -38 + 38 = 0

0 + 0.4k = 0.0 + 38

0.4k = 0.0 + 38

Combine like terms: 0.0 + 38 = 38

0.4k = 38

Divide each side by '0.4'.

k = 95

Simplifying

k = 95

What is the value of x
Nezavi [6.7K]

\tan(16)  =  \frac{8.3}{x}  \\

0.2867453858 =  \frac{8.3}{x}  \\

Thus :

x =  \frac{8 .3}{0.2867453858}  \\

x = 28.9455398797

Thus :

x = 28.9

Need help please! A=?
zubka84 [21]

Answer:

  m∠A ≈ 103°

Step-by-step explanation:

Enough information is shown for us to be able to use the Law of Sines to find the angle. That tells us ...

  sin(A)/a = sin(C)/c

  A = arcsin(a/c·sin(C)) = arcsin(26/6·sin(13°)) = arcsin(0.974788)

  A = 77.1° or 102.9°

The claim is that the figure is drawn to scale, so we can assume that A is an obtuse angle:

  m∠A ≈ 103°

__

<em>Additional comment</em>

The sum of angles A and B must be 180° -13° = 167°. Since angle A is the largest, it must be more than half this value, or more than 83.5°. That means, we must choose the obtuse angle for A, rather than the acute angle.
