Answer:
20 chickens
Step-by-step explanation:
2/8= 5/x
2 times 2.5 is 5, 8 times 2.5 is 20 the ratio is true if we write this:
2/8=5/20
Therefore, with 5 roosters, there are 20 chickens.
Answer:
The length of the island is 699 feet.
Step-by-step explanation:
Let the distance from the foot of the cliff to the near side be represented by x, and the distance from the foot of the cliff to the far side be represented by y.
Applying the trigonometric function to calculate the value of x;
Tan θ =
Tan =
0.2867 =
x =
= 1116.1493
x = 1116.15 feet
The distance from the foot of the cliff to the near side of the island is 1116.15 feet.
To determine the value of y;
Tan θ =
Tan =
0.1763 =
y =
= 1815.0879
y = 1815.09 feet
The distance from the foot of the cliff to the far side of the island is 1815.09 feet.
The length of the island = y - x
= 1815.09 - 1116.15
= 698.94
The length of the island is 699 feet.
Answer:
90, 70, 20
Step-by-step explanation:
The measure of an angle is 180 so if you add up 90,70,and 20 you get a total of 180
its sqrt(5) since sqrt(5) isn't a whole number(its like 2.23)
