Tan x =opposite/ adjacent =9/5
x= arctan(9/5)≈61
Answer:
The height of the trapezoidal base is 7.2 ft.
Step-by-step explanation:
Consider the provided information.
The volume of trapezoidal prism is the area of the cross-section × the length.

Where B is the area of base, H is the length and V is the volume.
The length of the prism is 25.2ft and volume is 1279.152


Hence, the base area is 50.76 ft².
The base is trapezoid.
The area of trapezoid is 
Substitute B=50.76,
in above formula.



Hence, the height of the trapezoidal base is 7.2 ft.
Answer:
y = -x - 3
Step-by-step explanation:
Plug in -1 for <em>x</em><em> </em>and your result will come out to 1 because of that double negative [-(-1) = 1]. Next, deduct 3 from 1 to get -2.

The average of the first three is 83 (85 + 90 + 74)/3
The average of the next 3 is 86.
The difference is 3
Answer:
y = -x + 1
Step-by-step explanation:
y - y1 = m (x - x1)
y-2 = -1 (x - (-1))
y -2 = -x-1
y = - x -1 + 2
y = -x + 1
