A tent guy line supports one of the upright tent poles. It runs from the top of the pole to a peg in the ground two and a half m

Inessa [10]

Answer:

258 cm

Step-by-step explanation:

Given:

Distance from the base of the pole to the base of a tent guy line is $2\frac{1}{2}$

Length of a tent guy line is 359 cm

To find: Height of the upright tent pole

Solution:

Let AB denotes the pole and AC denotes a tent guy line.

According to Pythagoras theorem, in a right angled triangle, square of hypotenuse is equal to sum of squares of other two sides.

$AC^2=AB^2+BC^2$

$AC=359 cm\\AB=x\\BC=2\frac{1}{2}\,m=\frac{5}{2}\,m=\frac{5}{2}\times 100=250\,cm$

Therefore,

$(359)^2=x^2+(250)^2\\128881=x^2+62500\\128881-62500=x^2\\66381=x^2\\x=257.6\,cm\approx 258\,cm$

FIrst, reciprocal means that you have to change the order of the fraction.

8 1/2 = 17/2

1 1/3 = 4/3

17/2 by the reciprocal of 4/3 = 17/2 by (this word means to multiply) 3/4

17/2 * 3/4 = 51/8 = 6 3/8
