Answer:

x = 2

Step-by-step explanation:

Start by combining like terms.

Collecting x terms onto the left side results in 8x;

collecting constants onto the right side results in 16.

Therefore, 8x = 16, and x = 2

The answer is x=2
1. Add 3x to both sides
2. Add 6 to both sides
3. Divide both sides by 8

A blimp is flying at a speed of 40mph and going in a direction of 80 degrees. After 3 hours of flying it turns and travels 1 hou

kykrilka [37]

Bearing is a topic that can be used to locate the position of an object at a given time. Therefore, the blimp is 80 m far away from its starting point. And in the North-East direction.

The speed of an object relates the distance it covers to the time taken to cover the said distance.

i.e speed = $\frac{distance}{time taken}$

⇒ distance = speed x time taken

In the given question, the initial distance covered can be determined as;

distance = 40 mph x 3 h

= 120 m

The final distance covered can be determined as;

distance = 40 mph x 1 h

= 40 m

Let the distance from its starting point to its final location be represented by x.

Thus applying the Cosine rule, we have:

$c^{2}$ = $a^{2}$ + $b^{2}$ - 2abCos C

$x^{2}$ = $120^{2}$ + $40^{2}$ - 2(120 x 40) Cos 90

= 14400 + 1600 - 9600

$x^{2}$ = 16000 - 9600

= 6400

x = $\sqrt{6400}$

= 80

x = 80 m

Therefore, the distance of the blimp from its starting point to its final destination is 80 m.
