Find the midpoint of the segment with the following endpoints.<br> (-3,6) and (3, 0)
otez555 [7]

The midpoint of the segment with endpoints (-3,6) and (3, 0) is (0, 3)

<h3>Midpoint of a line </h3>

From the question, we are to determine the midpoint of the segment with the given endpoints

The given endpoints are

(-3,6) and (3, 0)

Given a line with endpoints (x₁, y₁) and (x₂, y₂), then the midpoint of the line is

((x₁+x₂)/2, (y₁+y₂)/2)

Thus,

The midpoint of the line with the endpoints (-3,6) and (3, 0) is

((-3+3)/2, (6+0/2)

= (0/2, 6/2)

= (0, 3)

Hence, the midpoint of the segment with endpoints (-3,6) and (3, 0) is (0, 3)

Given: C∉ BD ,△ABC D∈ ray BC ,AB=AC=BC Prove: BD&gt;DA&gt;AB
jonny [76]

Triangle ABC is equilateral, because AB=BC=AC=a. Then

m∠A=m∠B=m∠C=60°.

Let point D lie on the ray BC to the right from points B and C and let CD=x. Then BD=a+x, AB=a.

Consider triangle ACD. In this triangle, m∠ACD=180°-m∠ACB=180°-60°=120°.

By the cosine theorem,

AD^2=AC^2+CD^2-2\cdot AC\cdot CD\cdot \cos \angle ACD,\\\\AD^2=a^2+x^2-2\cdot a\cdot x\cdot \cos 120^{\circ},\\\\AD^2=a^2+x^2+ax,\\\\AD=\sqrt{a^2+x^2+ax}.

Since a^2+x^2+ax=a^2+x^2+ax+ax-ax=(a+x)^2-ax, then

AD^2=(a+x)^2-ax

and

AD^2=a^2+x^2+ax>a^2=AB^2\Rightarrow AD>AB.

Therefore, you get double inequality

AB or BD>AD>AB.
