θ = 67.4°
Step-by-step explanation:
using the <u>SOHCAHTOA </u>method,
Here opposite is 12 cm, hypotenuse is 13 cm, adjacent is 5 cm.
Using the formula:
β = 67.4°
Since the perimeter is the sum of the length of all sides we multiply width and length by 2 and then add them together
Assume that 
and <span>multiply the equation 
by 4p. Then you obtain the equation 
.
</span>
1) If k>0, then 4pk>0 and the equation doesn't have solutions, because <span>
and this is unreal.
</span>
<span>2) If k=0, then 4pk=0 and
. There is one solution x=h.
</span>
2) If k<0, then 4pk<0 and the equation
<span>
has two different solutions 
and
