Let the estimated number of birds=x
Out of x birds, he tied a belt around the legs of 40 birds.
When he observed 520 birds, 34 of which had belts.
Expressing each as a ratio
Cross Multiply
34x=520X40
x=520X40÷34=611.7≈618
There are an estimated 618 birds.

Answer:
75°
Step-by-step explanation:
There are 180° in a triangle, so using the ratios and the 180° setup an equation. Solve for x.
5x + 9x + 10x = 180
24x = 180
24x/24 = 180/24
x = 7.5
To find the largest angle measure, use 10x since 10 is bigger than 5 and 9.
10x
10(7.5)
75°
