To measure the brightness of a star from earth, the brightness of the star Vega is used as a reference, and is assigned a relative intensity I(0) = 1. The magnitude m of any given star is defined by m = 2.5 log (I), where I is the relative intensity of that star.^7

(a) What is the magnitude of Vega?
(b) Suppose that light arriving from another star has a relative intensity of 5.32. What is the magnitude of this star?

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

+2+=+%2836%2fx%29%5e2+

+2+=+1296%2fx%5e2+

++x%5e2+=+1296%2f2+=+648+

25.45584

the answer will be b x² +x-1
