<u><em>Answer:</em></u>
The bird is approximately 9 ft high up in the tree
<u><em>Explanation:</em></u>
The required diagram is shown in the attached image
Note that the tree, the cat and the ground form a right-angled triangle
<u>Therefore, we can apply special trigonometric functions</u>
<u>These functions are as follows:</u>
<u>Now, taking a look at our diagram, we can note the following:</u>
α = 25°
The opposite side is the required height (x)
The adjacent side is the distance between the cat and the tree = 20 ft
Therefore, we can use the <u>tan function</u>
<u>This is done as follows:</u>
which is 9 ft approximated to the nearest ft
Hope this helps :)
Step-by-step explanation:
Wooden Cars = 2 × Wooden Trains
Ratio is
2 : 1
In total there are 3 parts
228 ÷ 3 = 76 (1 part)
Wooden Cars = 2 × 76 = 152
Wooden Trains = 1 × 76 = 76
Youd take two times nine and get 18 so it would be 18.55
