Question

Does anyone know the answer??
You have to find x.

Answer 1

9.01

Explanation:

The right angle triangle with a focused angle of degree is easily solved using Trig Ratio that can easily be recalled with this word :

SohCahToa.

What it means is:

If the Opposite side to the focused angle is given and also the hypotenuse is given, we use sine

Cosine if Adjacent and Hypotenuse is given.

Tangent if the opposite and Adjacent is given.

Now, to the question:

The Adjacent and the Hypotenuse is given. Therefore we'll use Cosine.

Therefore:

Cos 35 = x / 11

Cross multiplying:

11 cos 35 = x

11 * 0.8192 = x

Theresfore,

x = 9.01

Hope it helped?

Answer 2

Answer:x = 9.01

Explanation:

The given triangle is a right angle triangle.

From the given right angle triangle the hypotenuse of the right angle triangle is 17

With 35 degrees as the reference angle,

x represents the adjacent side of the right angle triangle.

The unlabelled side represents the opposite side of the right angle triangle.

θ = 35 degrees

To determine x, we would apply trigonometric ratio

Cos θ = adjacent side/hypotenuse side. Therefore,

Cos 35 = x/11

x = 11 Cos 35 = 11 × 0.8192

x = 9.01
