the perimeter of a scalene triangle is 14.5 cm. the longest side is twice that of the shortest side. which equation can be used

notka56 [123]

Let a = longest side
let b = shortest side
let c = third side

P = 14.5
a = 6.2
b = 1/2(a)

P = a + b + c
P = 6.2 + 3.1 + c

P = 9.3 + c

14.5 = 9.3 + c
c = 14.5 - 9.3
c = 5.2

Answer: $\sqrt{2}/2$ which is Choice B

This is the same as writing $\frac{\sqrt{2}}{2}$

The second "2" is not under or inside the square root.

==========================================================

Explanation:

Refer to the unit circle below. I've highlighted the angle 45 degrees and its corresponding sine value. It's the y coordinate of the point on the unit circle, for this particular angle.

Therefore, $\sin(45^{\circ}) = \frac{\sqrt{2}}{2}$

--------------

You could alternatively draw out a 45-45-90 triangle. Let x be the leg length and the hypotenuse is 1 unit long. Solve $x^2+x^2 = 1$ for x and you should get $x = \frac{\sqrt{2}}{2}$ as the length of each leg.
