Answer: given height of the whole is equal to 6 m hypertonus equals to 9 metre 9 square equals to 6 square + b square i.e. 9^2=6^2+b^2 81=36+b^2 81-36=b^2 45=b^2 b=√45 b=3√5 m н๏pε ¡т нεℓpร ყ๏น Reply

Answer:given height of the whole is equal to 6 m

hypertonus equals to 9 metre

9 square equals to 6 square + b square

i.e. 9^2=6^2+b^2

81=36+b^2

81-36=b^2

45=b^2

b=√45

b=3√5 m
