Question

Types of seeds on basis of presence and absence of endosperm

Answer 1

Answer:

Given: Two poles AB=11 m and CD=6m

Distance between both poles BD=12 m

Then, create a line segment CE parallel to line BD

So, AE=AB−CD=11−5=6 m

In right angled △AEC,

=144+25=169

⇒AC=13 m

So, the distance between their tops is 13 m.
