Answer: The pole is 3.5 foot above the right hand.
To answer this question first you need to determine the left hand height/position. The left hand divides the pole segment into 2:1 ratio. If the pole if 15 foot long, then the equation will be:
2/(2+1)x 15 foot= 10 foot.

The left hand is located 10 foot from the ground and the right hand is 1.5 foot above it. Then the right hand position from the ground is:
10 foot+ 1.5 foot= 11.5 foot

Since the right hand is 11.5 foot from ground and the pole is 15 foot long, then the equation will be:
15 foot- 11.5 foot= 3.5 foot.

Answer:

10

Step-by-step explanation:

Using trigonometry :

Taking the angle 45°

From trigonometry :

Sin θ = opposite / hypotenus

Opposite = s ; hypotenus = 10√2

Sin 45 = s / 10√2

Recall :

Sin 45 = 1/√2

We have ;

1/√2 = s / 10√2

s = 10√2 * 1/√2

s = 10√2 / √2

s = 10
