"x" would have to equal 1/2. You'd divide by 2 on both sides then simplify.
Here's what I did which might help you
4) They are congruent by ASA.
5) you can set up a proportion.
original height / shadow = original of tree/ shadow of tree
18/21 = x/14
21x = 252
x = 12
SO the height of the tree is 12
Hope this helps :)
For squrae
area=side²
perimiter=4(side)
for circle
area=pir²
circumference=2pir
side=diameter, diameter/2=radius=side/2
find area not covered
that is areasquare-areacircle
areasquare=26²=676 sqauare inches
areaciecle, diameter=side, 26/2=13, area=pi13²=169*3.14=530.66 square inches
areanotcovered=676-530.66=145.34 square inches not coverd
ratio of perimiter to circumferece
perimiter=4*26=104
circumference=2pir=2pi13=26pi=26*3.14=81.64
circumference to perimiter is 81.64/104=0.785
