Answer: 3/4
Step-by-step explanation:
Tangent is opp/adj
Therefore tan (x) = 18/24, which reduces to 3/4
Answer:
8 gallons
Step-by-step explanation:
Each rectangular face of the monument has an area of ...
A = bh = (9 ft)(39 ft) = 351 ft^2
The triangular face on top of that rectangle has an area of ...
A = (1/2)bh = (1/2)(9 ft)(10 ft) = 45 ft^2
So, one side of the monument has an area of ...
one side = (351 ft^2) +(45 ft^2) = 396 ft^2
The total area of all four identical sides is ...
surface area = (4)(396 ft^2) = 1584 ft^2
__
Each gallon covers 199 ft^2, to the number gallons required is ...
(1584 ft^2)/(199 ft^2/gal) ≈ 7.96 gal
Since only whole gallons can be purchased, 8 gallons of paint must be bought.
