Answer:
40°
Step-by-step explanation:
Base length, b = adjacent = 3020 feets
Height of building, h = opposite = 2534 feets
The angle of elevation formed :
Using the trigonometry relation:
Tan θ = opposite / Adjacent
Tan θ = 2534 / 3020
Tan θ = 0.8390728
θ = tan^-1(0.8390728)
θ = 39.999
= 40°
the answer is 45 because of the time
B because you are looking for an equation in the problem so if it starts at 16 and you are adding 2 gallons per hour you get 16+2x. Then for the other tank you start with 20 gallons and you are loosing 3 gallons per hour so you get 20-3x. To solve the equation you make them = each other so then you have 16+2x=20-3x.
Answer:
2a + 2b + 6c.
Step-by-step explanation:
To find this we subtract :-
3a + 5b + 7c - (a + 3b + c)
= 3a + 5b + 7c - a - 3b - c Now combine like terms:
2a + 2b + 6c (answer).
Answer:
-11x-3y^2
Step-by-step explanation:
(8x^2-9x^2-4x)+(x^2-3y^2-7x)
-x^2-4x+x^2-3y^2-7x
-4x-7x-3y^2
-11x-3y^2
