9. What is the measure of angle HJL in the picture below?
45
140
50
40

50

Step-by-step explanation:

j is 90 degrees and ljk is 40 degrees so you just minus it from 90 which will give you your answer.

50

Step-by-step explanation:So the angle is a right angle so take the 90 and subtracted by 40 and then you get 50

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
