Find the value of x. Round the length to the nearest tenth. The diagram is not drawn to scale.
Gekata [30.6K]

Answer:

x ≈ 2879.4 m

Step-by-step explanation:

Measure of ∠DAC = 10°

Measure of ∠DAB = 90°

Measure of ∠BAC = 90° - 10° = 80°

By applying cosine rule in ΔABC,

cos(80°) = \frac{\text{Adjacent side}}{\text{Hypotenuse}}

              = \frac{AB}{AC}

0.17365 = \frac{500}{x}

x = \frac{500}{0.17365}

x = 2879.36

x ≈ 2879.4 m

In order to be a triangle, the sum of two sides must be greater than the third side.  (Just think about it for a bit and you will see why this has to be true).  For example, could you have a triangle with side 3 inches, 4inches, and then a whopping 100 inches?  No, because the other two sides are too short to fully connect a triangle!

So once you understand this, we can find the possible length <span>of </span>the missing side.

Let x be the length of the missing side in centimeters.  The other two sides are 18cm and 40cm.

So one possible combination:

The sum of our two known lengths must be larger than the unknown length:

18 + 40 > x
58 > x

Therefore one constraint is that our third side has to be less than 58 centimeters.

Another combination:

18 + x > 40
x > 22

So another constraint is that our third side must be larger than 22 cm.

The last combination is pointless:

40 + x > 18

Since 40 is already larger than 18, then "40 + x" is obviously larger than 18.

So therefore our x has to be in this range:

22 < x < 58

In other words, our third side has to be larger than 22 cm, but less than 58 cm.
