Question 793000: the base,N,of an antenna rests on horizontal ground. the angle of elecation of the top R, from a point H on the ground is 42(degrees)
the angle of elevation of R from a second point, G, 6cm closer to N than H, is 53.2(degrees)
a)calculate
i)the length of RG
ii)the height RN, of the antenna
b)a third point c, lies on the ground 5.4m form N. the angle of depression of CfromR is x degrees
calculate to the nearest degree the vaule of x
