Let’s learn about indirect measurements. The problem says that
the triangles in the diagram below are similar and we need to
find the value of x, x is here. So let’s look at the similar
triangles. The triangles are RSU, we’re starting with right
angle coming towards the smaller angle and going up on top. So
here also we’ve got to start at the right angle which is here
similar to triangle T, come to the smaller angle which is S and
go up towards Q. It’s key to make sure that even though the
figures maybe arranged however they are, here the corner or the
right angle triangle is to the left here it’s to the right. We
need to make sure that we know what is the corresponding or
which the corresponding sides are. So here RS corresponds to TS,
US corresponds to QS sides which means QT on the side is the
same as UR this side. These are t
