Hello,
In this question, I am having trouble imagining what the diagram should look like. Am I finding the height of the triangle? I am feeling a little vexed...
An advertising balloon is attached to two ropes 120 m and 100 m long. The ropes are anchored to level ground 35 m apart. How high can the balloon fly?
Many thanks!
As I am new to simultaneous equations, please correct me if I am wrong:
x^2 + h^2 = 120^2 ....... (1)
(35 - x)^2 + h^2 = 100^2 ....... (2)
x^2 + h^2 = 120^2 ....... (1)
35^2 -70x + x^2 + h^2 = 100^2 ....... (2)
How do I proceed? Adding or subtracting x^2 or h^2 ?
