What is the length of the side labeled x cm?

UkoKoshka [18]

When we know 2 angles and one side, we use the Law of Sines.
First we need to find that third angle.
Angle A =
180 -41 -62 = 77 degrees

The Law of Sines states that

side a / Sine (A) = side x / Sine (X)
14 / Sine (77) = side x / Sine (41)

14 * Sine (41) / Sine (77) = side x

side x = 14 * 0.65606 / 0.97437
side x = 9.18484 / 0.97437

 side x = 9.4264396482

How do I solve for x? please explain

My name is Ann [436]

The aim here is to get all of the x's onto one side and the numbers onto the other side:

We can start by subtracting x from each side

2x+11=1

We can then subtract 11 from both sides

2x=-10

Finally, we can divide both sides by 2 leaving us with:

x = -5

-10x - 135 = 117 + 2x A. 25 B. -18 C. -21 D. 22 Helps pls

Lina20 [59]

Answer:

Step-by-step explanation:

Add 10x to both sides:

-10x - 135 = 117 + 2x

-10x - 135 + 10x = 117 + 2x + 10x

-135 = 117 + 12x

Subtract 117 from both sides:

-135 - 117 = 117 + 12x - 117

-252 = 12x

Divide both sides by 12:

$\frac{-252}{12} = \frac{12x}{12}$

-21 = x

So the answer is C.

Hope this helps!
