You are locked out of your house and the only open window is on the 2nd floor, 20 feet above the ground. You need to borrow a ladder from one of your neighbors. There's a bush along the edge of the house so you will have to place the ladder 15 feet away from the house. What length of the ladder do you need to reach the window?

how are u supposed to get the latter if your stuck in the house

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
