1st one I believe I’m not 100% sure
Answer: The central angle of the arc is 162 degrees.
Step-by-step explanation: The information available are as follows;
Circumference of the circle equals 10. Length of an arc equals 9/2. The circumference of a circle is given as;
Circumference = 2Pi x r
That means 2Pi x r = 10.
Also the length of an arc along the same circle is 9/2. Length of an arc is calculated as;
Length of arc = (X/360) x 2Pi x r
Where X is the central angle of the arc
That means;
9/2 = (X/360) x 2Pi x r
We can now substitute for the known values as follows
Length of an arc = (X/360) x 2Pi x r
9/2 = (X/360) x 10
9/2 = 10X/360
By cross multiplication we now have
(9 x 360)/(2 x 10) = X
3240/20 = X
162 = X
The angle at the center of the arc is 162 degrees.
6 times x (the variable) plus 14 so basically 6x+14
48 1/2 - (10 1/4 + 24 1/8) =
48 1/2 - (10 2/8 + 24 1/8) =
48 1/2 - 34 3/8 =
48 4/8 - 34 3/8 =
14 1/8 <=== so he is left with 14 1/8 inches of crown molding
