Answer:
BC = 18.34°
Step-by-step explanation:
The secant- secant angle BAC is half the difference of the intercepted arcs, that is
( DE - BC) = 27.42
( 73.18 - BC ) = 27.42 ( multiply both sides by 2 )
73.18 - BC = 54.84 ( subtract 73.18 from both sides )
- BC = - 18.34° ( multiply both sides by - 1 )
BC = 18.34°

Step-by-step explanation:
Missing question:
An artist is making a rectangular canvas for a custom painting. the canvas has a width of 9 1/2 feet and a length of 13 1/4 feet . what is the area of canvas in square feet?
The area of a rectangle is given by the formula
(1)
where
A is the area
L is the length
w is the width
In this problem, we have a rectangular canvas, so we want to find its area.
We know that:
is the width, converting into an improper fraction,
ft
is the length, converting into improper fraction,
ft
Substituting into eq (1), we can find the area of the canvas:
