Answer:The answer will be 35ft

Step-by-step explanation:

One way that you can answer this is by using sin law. You will put the length of a side on top and the corresponding angle that faces towards that side at the bottom of a fraction. So for this one it will be 30/sin(70) = x/sin(90) The 90 comes from the bottom of the building with the ground. And the side the angle faces is the ladder. After that you put 30sin(90)/sin(70) to find x. And you get 34.655 which rounds to 35 ft.

Which is not a valid range? a1:a3, b1:b3 a1:a9 a1:f9 a1:f1?
Maru [420]
<span>a1:f9 is not an valid range because it has neither a row nor a column in common. This contrasts with a1:a3, b1:b3, and a1:a9 which each have a row in common, as well as with a1:f1, which has a column in common. In general, to make a valid range coordinates must be specified that allow a single row or column of cells to be specified.</span>
