Draw a diagram

we need to find the area of the other leg

alright

we have one leg is 16.4
the other one is ?
tan(29°)=?/16.4
16.4tan(29°)=?
and the height of the nest is ?+height of camera=?+1.8

so
16.4tan(29°)+1.8≈10.8907
so about 10.9m

Answer:

p=114

Step-by-step explanation:

Let K=m/p=8/3 proporcionality constant. if m=304 then p=?

m/p=8/3; 8/3=m/p; p(8/3)=m; p=(3/8)m; replacing m we have  p=304(3/8) finally p=114
