JulsSmile [24]

How far is the kicker from the right post, to the nearest yard is: 23 yards.

<h3>Distance</h3>

Using sine theorem

Let y represent the numbers of yards

Left triangle=3/sinx=14/sin∝

Right triangle=5/sinx=y/sin(180-∝°)

sin∝°=sin(180-∝°)

Hence,

3/5=14/y

y=5×14/3

y=23 yards

Therefore how far is the kicker from the right post, to the nearest yard is: 23 yards.

____ [38]

9514 1404 393

Answer:

  • up the wall: 4√3 ft ≈ 6.9 ft
  • along the ground: 4 ft

Step-by-step explanation:

The side ratios in a 30°-60°-90° triangle are 1 : √3 : 2. Since the hypotenuse of this triangle is 8 feet, the multiplier of these ratio values is (8 ft)/2 = 4 ft.

The triangle sides are ...

  4 ft : 4√3 ft : 8 ft

The ladder reaches 4√3 ≈ 6.9 ft up the wall. Its base is 4 ft from the building.

How many miles will his family travel on the first day?
Igoryamba
On the first day, they traveled for 10 hours with an average speed of 60 mph.  Which means on the first day they traveled 600 miles.

Since the total distance is 1023 miles and presumably they will be going at a speed of 60 mph.  We divide the miles by the rate:

1023/60  = 17.05

So it will take 17.05 hours to drive the whole way to Florida.
