Answer:
y = 7
Step-by-step explanation:
Firstly multiply each and every term by 9
17/9 - y/3 = -4/9
; 17 - 3y = -4...then move the variabkes without (y) to one side,
; 21 = 3y....then divide both sides by 3
; 7 = y
;Hence..., y = 7
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 :)
