x =  35

Your answer is correct you just have to write it as "x=35" with no spaces or uppercase letters

Step-by-step explanation:

Both sides need to be added and set equal to 180°.

2x - 5 + 3x + 10 = 180

Add/subtract like terms.

5x + 5 = 180

Subtract 5 from both sides to begin to isolate the variable.

5x + 5 = 180

    - 5      -5

5x = 175

Divide 5 from both sides to completely isolate the variable.

5x/5 = 175/5

x = 35

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
