320 x (0,015^18) x 100

4,73

4.729

Step-by-step explanation:

320 * 0.015^18 * 100

320 *100 = 32000

32000 * 0.015^18

0.0015^18 = 1.4778

32000 * 1.47789

4.72925

the correct answer is x/3+10≥32

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
