QUESTION 4
Find the height of the pole where the guy wire is attached, to the nearest tenth of a metre.
c² - b² = a²
10² - 2² = a²
(10x10) - (2x2) = a²
(10x10) - (2x2) = a²
100 - 4 = a²
96 = a²
√¯96 = √¯ a²
9.8 = a
The height of the pole is 9.8 metres.
9.8 = a
The height of the pole is 9.8 metres.
Again I'm sorry that it's late. Hope I made you happy Harbeck !

I think when you put 9.8 = a², it's just supposed to be 9.8 = a. Otherwise, good job Vanessa :)
