Answer:

There is one theorem in triangle which states that sum of any two sides of a triangle is greater than the third side. For example, if a,b and c are three sides of a triangle, then a+b>c, b+c>a and a+c>b.

So, we will use here same concept.

Let a=5cm, b=7cm and c=12cm

a+b = 5+7 = 12cm which is equal to c.

<em>But a+b should be greater than c.</em>

Therefore, the triangle doesn't exist.

Answer:

$\frac{3}{2} x -4$

Step-by-step explanation:

Given expression:

$- \frac{1}{4} ( - 6x + 16)$

Distribute the -1/4:

$(- \frac{1}{4} \times - 6x )+ ( - \frac{1}{4} \times 16)$

Simplify:

$\frac{6x}{4} - 4 = \frac{3}{2} x - 4$

Evaluate sin 300° without using a calculator.

Anni [7]

Answer:

$-\sqrt{3} /2$

Step-by-step explanation:

300 degrees is in the fourth quadrant (it's between 270 and 360); sine is negative in the fourth quadrant.

Given we're in the fourth quadrant, the reference angle is 360 - 300 = 60 degrees

sin(60°) = $\sqrt{3} /2$

And since sine is negative, this value turns negative:

sin(300°) = $-\sqrt{3} /2$

The length of a side of a triangle is 36. A line parallel to that side divides the triangle into two parts of equal area. Find t

pantera1 [17]

Answer:

18√2

Step-by-step explanation:

The area of the smaller triangle is 1/2 that of the larger one. Since the triangles are similar, the dimensions of the smaller triangle are √(1/2) those of the larger one.

36 · √(1/2) = 36 · (√2)/2 = 18√2 . . . . length of line dividing the triangle
