a lighthouse is 27 m above water. a boat is 98.7 m from the base of the lighthouse. Make your own sketch and calculate the angle of depression of the boat from the top of the lighthouse. Give your answer to the nearest one-tenth of a degree.​

dont understand

step-by-step explanation:

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down

they can both be solutions depends on the equation

step-by-step explanation:

what is the equation? ?

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.
