Can someone me with this word problem?

So for question 7 part A the picture will be a triangle similar to the the one that shows the umbrella's height. But the base will be 40 and the height will be 130.

for part B the angle of depression can be found using the trigonometric function of tangent.

tan x = 40/130
tan^-1 (tan x) = tan^-1 (40/30)
x = 17 degrees

I hope i am right

59/96 is the ratio hope this not 100% sure though : /
