Using trigonometry (SOHCAHTOA), <WZX is our main angle that we will be using. Our H or hypotenuse is the ZX or 7 because it is longest side in the triangle XZW, the A or adjacent is ZW or X. Then you set up your equation using the CAH of SOHCAHTOA and solve. To find WX, you use the same H or hypotenuse is the ZX or 7 because it is longest side in the triangle XZW and the O or opposite is WX which is your X. For setting up your equation you use the SOH of SOHCAHTOA and solve. You then double each of your measurements you got for ZW and WX and add them together to get your perimeter. Good luck! Let me know if you still need help!
Please, share just ONE problem at a time. Thanks.
<span>Solve 2x^2-12x+20=0:
Simplify this by dividing each term by 2: x^2 - 6x + 10 = 0
Identify a, b and c: a=1, b=-6 and c=10. Then b^2=36.
Write out the solutions using the quadratic formula:
6 plus or minus sqrt(36-40)
x = ---------------------------------------
2
sqrt(36-40) = sqrt(-4) = plus or minus i2
Then:
6 plus or minus i2
x = --------------------------- (answer)

This is an arithmetic sequence, since it's pattern is +4.
n1 = 1
d = 4
n = 1 + (n-1)(4) <-------------- This is the formula for the nth term of the sequence.

Answer:
{4, 5, 6, 7, 8}
Step-by-step explanation:
The inequality related to the perimeter is ...
x +(x +4) +11 < 32
2x < 17 . . . . . . . . . . . . subtract 15
x < 8.5
The inequality related to the triangle inequality is ...
(x) +(x +4) > 11
2x > 7
x > 3.5
Then possible whole-number values of x are ...
{4, 5, 6, 7, 8}
