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.

For a triangle ot be created the shortest two sides must add up to a number greater than the longest side. IE 1.6 + 5.9 = 7.5, therefore one triangle CAN be drawn.

However the order of the sides can be clockwise or anti-clockwise so more than one trinagle can be drawn .

John got a 76, 68, and 83 on his first three test. What score does he need on his fourth test to achieve an 80 average?

shepuryov [24]

It's 93.
simple calculate it by:
(76+68+83+x)/4=80
then 73*5-(67+75+73+69)=x
where x here is the grade needed to reach an av. of 80. 4 is the number of tests.
