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
