Question 189332This question is from textbook algebra and trigonometry structure and method book 2
: Please help me with this. I don't get the formula. I could guess and probably come up with the right answer but I need to know how to come up with a formula. I tried drawing the diagram but it didn't help me and i don't know where to begin or how to turn it ito a quadratic equation because i think that's what they want. Please be detailed in your answer.
