Question 1045667: I need help with this question.
In order to rescue Max's cat, his father propped a 19 foot long ladder against a tree at a 42 degree angle with the ground. How many feet above the ground was his cat. Round your answer to the nearest tenth of a foot.
Thanks

The height up the tree is the adjacent angle in a triangle
where 19 feet is the hypotenuse.
Cosine is the ratio of the adjacent/hypotenuse
So cos(42 degrees) = height/19
Since cos(42 degrees) = approximately 0.7431
set h = height
0.7431 = h/19
multiply each side by 19
19(0.7431) = h
h = 14.12 approximately
Rounded to the nearest 1/10 foot = 14.1
