Answer:
10.6..... I think
Step-by-step explanation:
we know that the latter is 8ft tall and the angle it makes with the ground is 60. The ground is opposite to the angle the ladder forms with the ground so 8sin60 gives us the length of the building(6.928203230275 or 7). then using pythagorean theorem.a^2+b^2 = c^2 we can do 8^2+ 7^2 = c^2 or 64+49=c^2, 113= c^2. Then to get the value of c you would do the square root of 113 which is 10.63014581273 or 10.6
