Question

two poles of heights 6m and 11m stand on a plane ground.if a distance between feet of poles is 12m find distance between them

Answer 1

THE DISTANCE BETWEEN THEM IS 12²+5²=X²
X²=144+25=169 AND √169=13
THUS THE DISTANCE BETWEEN THEM IS 13m

Answer 2

Q- Two poles of heights 6m and 11m stand on a plane ground.if a distance between feet of poles is 12m find distance between their Tops. (Correction)

S- Let's make a rough figure, and let the first pole of 6m is AB (as in fig.) Second pole of 11m is CD (fig.)

So, let's draw AO parallel to BD which cuts CD at O , dividing CO and OD of 5m and 6m respectively.

So, AO = 12m and OC = 5m

Distance between A and C will be given by Pythagorean theorem →

AC² = AO²+CO²

or, AC² = 12²+5²

or, AC² = 144+25

or, AC² = 169

or, ✓AC² = ✓169

or, AC = 13m

Therefore , the distance between tops of the pole is 13m
