The temperature at 7 AM was 1° the temperature drops 3° every hour for four hours what temperature at 11 AM

-11 degrees

Step-by-step explanation:

At 7 am the temperature is 1 degrees, then, an hour later, its drops by 3 degrees (1-3) which equals -2 degrees, then it drops by 3 again, (-2-3), making it -5, then it drops again, (-5-3), making it -8 degrees, and then it drops one last time, (-8-3), making it -11 degrees.

(P.s, I hope this is Celsius)

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
