For AD:
AD=root((c-0)^2 + (d-0)^2)=root((c)^2 + (d)^2)
For BC:
BC=root(((b+c) - b)^2+(d-0)^2)=root((c)^2+(d)^2)
For AB:
AB=root((b-0)^2 + (0-0)^2)=root((b)^2 + (0)^2)=root((b)^2)
For CD:
CD=root((c-(b+c))^2 + (d-d)^2)
CD=root((b)^2 + (0)^2)
CD=root((b)^2)
This one looks very tricky but ill try it out
It is centered at (h,k) --> (0,0) and has a radius 9
The equation of the circle is

Hope that helps!
Your answer for -16 divided by 2 will be -8, because half of 16 is 8, but you are just in the negative numbers:)! So your answer is -8
Given:
In ΔKLM, l = 48 inches, ∠K=55° and ∠L=46°.
To find:
The length of k, to the nearest inch.
Solution:
According to Law of sine,

In ΔKLM, using law of sine, we get



On further simplification, we get



Approximate the value to the nearest inch.

Therefore, the length of k is 55 inch.
