Answer:
The depth of the water is 42 ft
Step-by-step explanation:
The volume of the rectangular tank = base area × height
The water will take the shape of the tank
So the volume of the water = the area of the base of the tank × the height of the water
94,500 = 25 × 90 × h water
h water = 94500 ÷ (25 × 90) = 42 ft

Answer:
(a)
Step-by-step explanation:
using the following
The sum of the 3 angles in a triangle = 180°
The sum of the angles on a straight angle = 180°
To find x subtract the sum of the 2 given angles in the triangle from 180
x = 180 - (56 + 38) = 180 - 94 = 86 ( sum of angles in a triangle )
To find z, subtract x from 180
z = 180 - 86 = 94 ( angles on a straight angle )
To find y subtract the sum of the 2 angles from 180
y = 180 - (94 + 19) = 180 - 113 = 67
x = 86, y = 67 and z = 94
