Question

A person of height 150cm is 12.5cm away from a coconut tree. The angle of elevations is 45 what is the height of the tree

Answer 1

Answer:

Step-by-step explanation:

•   CONSIDER A RIGHT ANGLED TRIANGLE 'ABE'. RIGHT ANGLED AT B AND 45° AT E.
• PRODUCED C DOWNWARD FROM AB AND PRODUCED D DOWNWARDS FROM E.
• ED = BC = 150 CM ( ED = PERSON HEIGHT AND EBCD IS PARALLELOGRAM )
• TAN45° = AB / EB

      1 = AB / 12.5

       AB = 12.5 CM

• HEIGHT OF COCONUT TREE = AB + BC

     12.5 + 150 = 162.5 CM
