Answer:
21.8 m
Step-by-step explanation:
The tangent function relates this angle, height and horizontal distance:
height
tan 23.6 degrees = --------------
50 m
Then the height of the building is (50 m)(tan 23.6 degrees) = 21.8 m
So basically you are saying that 80% of ____ games is 32 games.
So 32 is the 80% of the games played.
so we can divide 32 by 8, and that will give us 4 ( you might be confused why I did this, just be patient please)
so 4 is 10% of the games played.
We have to find out 20%, so we just multiply 4 by 2, which is 8
too find out 100%, we just add 80% and 20%, so 32 was 80%, and 8 was 20%, and 32 + 8 = 40
So the answer would be 40.
