P and Q are two observation posts on the same horizontal ground as the foot R
of a vertical pole RT. P is 2.5 km south
of R. Q is east of R and is on a bearing
of 065° from P. The angle of elevation
of T from P is 40°. Calculate, correct to
three significant figures:
i) sketch the diagram
ii) the distance RT
iii) the distance RO
iv) the distance PQ
v) the angle of elevation of T from Q.​

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
