The answer is 26.19. It’s 100% right.
For this case we have the following expressions:
70,000,000
7,000,000
If we divide the first expression by the second we have:

Thus, we have that the first expression is 10 times greater than the second expression.
Answer:
70,000,000 is 10 times greater than 7,000,000
For this case what we must do is use the law of cosines.
We then have the following equation:

Where,
a, b: sides of the triangle
x: angle between sides a and b.
Substituting values we have:

Clearing the value of c we have:
Answer:
An expression that is equivalent to how many feet the oak trees are from each other is:
Answer:
width = 115 cm
Step-by-step explanation:
width² = 277² - 252²
width² = 76729 - 63504 = 13225
width = 115 cm
