From a tower 150 feet high with the sun directly overhead, an airplane and its shadow have an angle of elevation of 66.5degrees and an angle of depression of 7.3degrees, respectively. find the height of the airplane.

answer is  

a.

7 in. x 11 in.

hope you get this right.

the answer is c.) yes, [triangle]klp can be reflected across the line containing [line]kp and then translated so that p is mapped to m.

the reason is this:

looking at the triangles visually we can see they share the same features. using rigid transfromations we can reflect it over [line]kp then all we need to do is translate up.

the answer is b

576 cm2

hope i got it for you : )
