Answer:
Step-by-step explanation:
We want to find equation of a circle with center (-4,6) and radius 9cm.
The equation of a circle with center (h,k) and radius 
units is given by;
We substitute the radius and the center to obtain;
The required equation is:
Answer:
Step-by-step explanation:
Parallel lines in this kind of triangle are always in a strict ratio of small to large or large to small based on how you look at it. So we have 4cm to 6cm, which is 2:3 ratio. We know the smaller side, but want the larger side, so we can set up 2/3 = 10/? the ? is 15.
Write it as a mixed fraction 7/5 = 1 2/5
Rewrite = so is on the left side.
