Since you were given all three sides, you can use Heron's formula to find the area.

Heron's formula: A = square root[ s * (s - a) * (s - b) * (s - c) ] where a, b, and c are sides of the triangle and s is the semiperimeter (a + b +c) / 2

Let's solve for s first:

s = (14 + 17 + 12) / 2

s = 43 / 2

s = 21. 5

Now plug in the values into Heron's formula:

A = square root [ 21.5 * (21.5 - 14) * (21.5 - 17) * (21.5 - 12) ]

A = square root [ 21.5 * (7.5) * (4.5) * (9.5) ]

A = square root [6893.4375]

A ≈ 83.067

A ≈ 83

IDK  I'm lazy lol

you need to have x by its self on on e side of the equation. You can do this by taking the square root of each side. 

It's probably in base 12

just press enter an extra time

2nd answer is actually 10.83%. The other one forgot to subtract the faulty ones from the total

\(\sqrt(564536)=\sqrt(4*141134)=2\sqrt(141134)=2\sqrt(2*37*191)\)

Need either the angle between the sides or the third side to solve this

It's either 0 or undefined, since 0*anything=0

If it terminates, put it over 10^x+1, x=# of decimal places

If it repeats: (repeating digits)/9(\(\sum{10^{-y}}_{y=1}^{x}\)), x= # of repeating digits

If it does neither, raise it to a power and then try

If it's a whole number, put it over 1

If it's \(\pi\) or \(e\) put it over 1

Q3->Q1=(x-180)º= (234-180)º=54º

cosine<0 in Q3

Solve for a:
2000 = 11.7888 a (a+0.17)

11.7888 a (a+0.17) = 7368/625 a (a+17/100):
2000 = 7368/625 a (a+17/100)

2000 = 7368/625 a (a+17/100) is equivalent to 7368/625 a (a+17/100) = 2000:
7368/625 a (a+17/100) = 2000

Multiply both sides by 625/7368:
a (a+17/100) = 156250/921

Expand out terms of the left hand side:
a^2+(17 a)/100 = 156250/921

Add 289/40000 to both sides:
a^2+(17 a)/100+289/40000 = 6250266169/36840000

Write the left hand side as a square:
(a+17/200)^2 = 6250266169/36840000

Take the square root of both sides:
a+17/200 = sqrt(6250266169/921)/200 or a+17/200 = -sqrt(6250266169/921)/200

Subtract 17/200 from both sides:
a = sqrt(6250266169/921)/200-17/200 or a+17/200 = -sqrt(6250266169/921)/200

Subtract 17/200 from both sides:
Answer: |
 | a = sqrt(6250266169/921)/200-17/200 =~12.940                                                                                  a = -17/200-sqrt(6250266169/921)/200= -13.110

hey omi67, you suck

What is right? 1, 2 or 3

You must put brackets!

279cm + 23cm = 302cm

 Using the Ambiguous Law of Sines, solve the following triangle.

1.5=3/2

(3/2)/(3/16)=(3/2)*(16/3)=16/2=8

\({1.5\over{3\over16}}= {{3\over 2}\over{3\over16}}= {3\over2}*{16\over3}={16\over2}=8\)

pen is

3 x − (2 − x) + 1

= 3x -2 + x +1

= 4x -1

= 2(2x) - 1

-5+ 4x +4

= 2(2x) - 1

We can factor out a x^2

y = x^2(x + 3)

Solve for 0

0 = x^2(x + 3)

Either x^2 is 0 or (x + 3) is 0.

If (x + 3) is 0 then x = -3

If x^2 = 0 then x= 0 or x = 0 (it's square; there's two roots x*x)

So the roots are: 0, 0, -3. Use both zeros; since it's a cubic expression, there are 3 roots.

If h is zero, then the area A is zero also, so b would be indeterminate.

Just type 25 - 1/2 in the calculator, and it'll do it for you ;)

That's what the calculator is for, not the forums.

Slope-intercept form is y= mx + b

Slope m = (y2 - y1) / (x2 - x1)

m = (2 - 8) / (-6 - 3)

m = (-6)/(-9)

m = 2/3

Now we can solve using the point-slope form y - y1 = m(x - x1) using either point for our x1, y1 (doesn't matter which).

y - 8 = (2/3)(x - 3)       Here i used point (3, 8) and our slope (2/3) from above.

y - 8 = (2/3)x - 2          Distribute the (2/3)

y = (2/3)x + 6               Add 8 to both sides

Therefore the slope-intercept form is y = (2/3)x + 6

When solving for slope, (8 - 2)/( 3 - -6) is just as valid as (2 - 8)/(-6 - 3) but (8 - 2)/(-6- 3) is not. Keep the x's and y's in the same order as each other and the y's on top (rise over run).
