Find the value of x if DE is the midsegment of triangle ABC and
Varvara68 [4.7K]

Answer

Find out the value of x.

To prove

Definition of mid- segment

It is a segment connecting the midpoints of two sides of a triangle.

It is always parallel to the third side, and the length of the midsegment is half the length of the third side.

As shown in the triangle given below.

As given

DE = 5x and BC = 11x – 15

Thus

DE = \frac{BC}{2}

5x = \frac{11x-15}{2}

5x\times 2 = 11x-15

10x = 11x-15

15 = 11x - 10x

15 = x

Therefore the value of x is 15 .

                    x

Use tangent to find the x.

tan(2) = \frac{100}{x}

x = \frac{100}{tan(2)}

Use a calculator to evaluate.

x = \frac{100}{tan(2)} = 2863.6253

So, the boat is 2,863.63 feet from the shore.
