Find the area of the shaded sector (it is 45 degrees with a radius of 7) !

Step-by-step explanation:

The formula for the area of a sector is

where theta is the angle given as 45 and r is the radius (7).  Plugging in we get

Simplify a bit to get

which gives you, in terms of pi:

or if you need to use the decimal form, rounded to the hundredths position:

A = 19.24

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
