Question

Two poles stand on the opposite sides of a road, 10 m wide. The
heights of the two poles are 7 m and 9 m respectively. Estimate the
distance between their tops, nearest to the whole number of metres.​

Answer 1

Answer:

by pythogoras theorem = H×H=A×A+B×B

H×H={2×2}+10×10

H×H= 4+100

H×H=104

H=√104

H=10.20 m
