How do i Solve: X-1<3

x = 2 OR 3

Step-by-step explanation:

I haven't done this maths in a long time but when you look at this symbol < just imagine it's crocodile's mouth. The crocodile likes bigger meals (the bigger number which is 3). So, if you do 2 - 1 = 1 or 3 - 1 = 2, both 1 and 2 are smaller than 3.

x<4

Step-by-step explanation:

x−1<3

Add 1 to both sides.

x<3+1

Add 3 and 1 to get 4.

x<4

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
