Answer:
<u>19.17 feet</u> of lace will be leftover.
Step-by-step explanation:
Given:
Kaitlyn is making a quilt she purchased a 46 feet long piece of lace to sew around the edges of the quilt she needs 322 inches of lace for the quilt.
Now, to find the feet of lace will be leftover.
<u><em>Total feet of lace =</em></u> <u>46</u>.
Kaitlyn needs lace for the quilt = 322 inches.
So, by using conversion factor we change inches into feet:
12 inches = 1 foot.
322 inches =
<u><em>Feet of lace she need for the quilt =</em></u> <u>26.83</u>.
Now, to get the feet of leftover lace:
<u><em>Total feet of lace - feet of lace she need for the quilt</em></u>
Therefore, 19.17 feet of lace will be leftover.
Answer:
Part 1)
Part 2)
Part 3)
Step-by-step explanation:
Part 1) Find the measure of angle ECF
we know that
CF is tangent at point C
so
the radius EC is perpendicular to the tangent CF
therefore
Part 2) Find the measure of angle AKB
we know that
The measure of the interior angle is the semi-sum of the arcs comprising it and its opposite
substitute the values
Part 3) Find the measure of angle ACF
we know that
The inscribed angle is half that of the arc it comprises
substitute the values
