Commutative property I hope this helps
Cos x = 15÷17
because cos is adjacent side over hypotenuse.
120/4=30. Remember its widthxlength. if you forget ask your teacher or look online for more help. Good luck.
Answer:
The tree is 28 feet tall.
Step-by-step explanation:
It is given that:
Height of flag pole = 8 feet
Shadow of flag pole = 6 feet
Ratio of height to shadow = 8 : 6
Shadow of nearby tree = 21 feet
Height of nearby tree = x
Ratio of height to shadow = x : 21
8 : 6 :: x : 21
Product of means = Product of extremes
6x = 8*21
6x = 168
Dividing both sides by 6

Therefore,
The tree is 28 feet tall.
That's great!
Maybe you should use that to help others, in person, on video call, in a group, your family, or even on Brainly!
