Triangle FGH has a right angle at ZG. If cos F
cos F = 12. What is the value
of sin ?

A. A zip line begins 50 ft above the ground in an oak tree, crosses a field, and ends in a maple tree. The trees are 125 ft apart. The zip line is at a 15° angle of depression.

A. Find the length of the zip line. Round to the nearest tenth of a foot.

B. What is the height, from
the ground of the endpoint of thezip line?

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
