Answer:
23.54 m
Step-by-step explanation:
Applying
cos∅ = adjacent(A)/hypotenuse(H)
cos∅ = A/H................ Equation 1
make H the subject of the equation
H = A/cos∅............ Equation 2
Given: A = 15 m, ∅ = 25°
Substitute into equation 2
H = 15/cos25
H = 16.55 m
Also,
tan∅ = opposite(O)/Adjacent(A)
tan∅ = O/A............Equation 3
Make O the subject of the equation
O = Atan∅.......... Equation 4
Substituting into equation 4
O = 15(tan25°)
O = 6.99 m.
From the diagram,
The height of the goal post before snap = H+O
The height of the goal post before snap = 16.55+6.99
The height of the goal post before snap = 23.54 m
Answer:
Step-by-step explanation:
The area of the swimming pool will be equal to 
.
We know that the length is 
and the width is 
.
Therefore we can substitute those into the equation:
Then, we expand the brackets using a grid (attached).
After this, we collect like terms to find the final answer:
Our final answer is:
29) 1/2
30) 3/5
31) 3/4
32) 8/10 equal 4/5
