The angle of elevation of the top (T) of a palm tree from a point (R) on the ground is 30°. The distance from R to the base (B) of the palm tree is 120m. What is the distance between T and R?

the question shows that R is the base of observation which is 30⁰ while T is the top where of the observation from R the distance between R and the foot of T is 120
thereby the distance of observation RT was asked to be calculated
thus giving the equation
cos 30⁰ = hypotenuse/120cm
cos 30° is the same as √3/2
√3/2=hypotenuse/120cm
hypotenuse =120 x √3/2
hypotenuse=60√3cm
