Will mark brainliest (part two) lol

1. The rope touches the top of the tree, then by similar triangles, the building must be  

32 feet tall.  

4. The perpendicular bisectors of the three sides of a right triangle intersect on the hypotenuse.  

Since that's on the triangle, rather than inside or outside it, the answer is  

II only.  

A triangle could have sides of 6 cm, 10 cm, and 9 cm.  

(In all the other answers, the two shorter sides add up to the length of the larger side or less than that length, so they can't form a triangle.)  

If the lengths of two sides of a triangle are 9 and 15,  

then the third side must be more than 15 - 9 = 6  

and less than 9 + 15 = 24.
