Answer: The distance between the birds is about 77.78 yards.
This is a trigonometry problems, so it helps to draw a right triangle between the birds. The length between them is the hypotenuse and we have a angle of 40 degrees by the sparrow. The side opposite the sparrow is the difference in heights of the birds, 50 yards.
Therefore, we can write and solve the following sine relationship.
sin(40) = 50/x
0.6428 = 50/x
x = 77.78 <span />
Answer:
= 1/5 ( 0.2 in decimal )
Step-by-step explanation:
3(-1/6) (-2/5)
= 1/5 ( 0.2 in decimal )
We can solve this problem using the Pythagorean Theorem. The Pythagorean Theorem states, that with hypotenuse c, and legs a and b, a² +b² = c², and since this is a right triangle, that principle is true here. In this problem, we have the length of the hypotenuse and leg a. So, we can insert the values of the variables and then simplify to find out the length of b. 15²+b²=20²b²=400-225b²=175b=√175
