Answer:
57.3°
Step-by-step explanation:
A 25 feet ladder leans against a building.
The ladder's base is 13.5 feet from the building.
The ladder, the wall of the building and the ground form a right-angled triangle of:
Hypotenuse = 25 feet
Base = 13.5 feet
We are to find the angle of elevation which the ladder makes with the ground (or rather the angle created by hypotenuse and base)
Let's say the angle = X°
According to a trigonometric equation;
cos X° = adjacent side ÷ hypotenuse = 
= 0.54
= 57.5=3° (Answer rounded up to nearest one decimal place).
∴ The angle of elevation = 57.3°

Answer:
25 ft
Step-by-step explanation:
The volume is given by the formula ...
V = LWD . . . . . the product of length, width, depth
Solving for L, we have ...
L = V/(WD) = (1700 ft³)/((17 ft)(4 ft)) = 100/4 ft = 25 ft
The length of the pool is 25 ft.
To solve this question, plug in the ordered pairs given (note it is (x,y) ) into the equation.
(B) The x-intercept is (0,6) and the y-intercept is (-3,0)
4x - 2y = -12
x-intercept:
4(0) - 2(6) = -12
0 - 12 = -12
-12 = -12 (True)
y-intercept:
4x - 2y = -12
4(-3) - 2(0) = -12
-12 - 0 = -12
-12 = -12 (True)
