9 + 3 + 17xy² + 8y³ + 10x - 13xy² - 9x - 6y³
12 + 17xy² + 8y³ + 10x - 13xy² - 9x - 6y³
17xy² - 13xy² + 10x - 9x + 8y³ - 6y³ + 12
4xy² + x + 2y³ + 12
The answer is A.
Answer:
#7 is congruent
#8 is not congruent
Step-by-step explanation:
#7 is congruent because of the angle angle side triangle congruency theorem.
#8 is not congruent because it’s properties don’t match with any of the triangle congruency theorems.
Add the numbers they equal 30 then u divide 30 by 2 since it’s an odd number and you get 15. so 15 is your answer
Answer:
Which grade's question is this?
The height of the tree is 249.5 feet
<h3>How to determine the height of the tree?</h3>
The given parameters are:
- Elevation angle = 80 degrees
- Shadow length (L) = 44 feet
Let the height of the tree be x.
So, we have:
tan(80) = x/44
Multiply both sides by 44
x = 44 * tan(80)
Evaluate
x = 249.5
Hence, the height of the tree is 249.5 feet
