Answer:
Angle A = 18°
Step-by-step explanation:
since the angles are complementary, they add up to 90°
(2x-4) + (5x+17) = 90
add like terms
7x-4+17=90
simplify left side
7x+13=90
subtract 13 from both sides
7x=77
divide both sides by 7
x=11
plug in x to find the measure of angle A
2(11) - 4
multiply 2*11 first
22-4
simplify
18
Perimeter = 2l + 2w
Divide 184 by 4
184/4 = 46
Subtract by 6
46 - 6 = 40
Add by 6
46 + 6 = 52
The length is 52, and the width is 40.
We can verify by plugging these values into the original equation.
52*2 + 40*2 = 184

Answer:
292 inches^2
Step-by-step explanation:
So to start off this is a picture of the fish tank.
Next we will find the area of the bottom and top rectangles.
The side lenghts for those two is 7 and 8.
So the area of one is 56 and the area of 2 is 112 inches^2.
Now we will find the area of the left and right rectangles.
The side lenghts are 6 and 8.
So the area of 2 is 96 inches^2.
Now for the front and back rectangles.
The side lenghts for those two are 6 and 7.
So the area of both is 84 inches^2.
So after adding all the areas up the surface area is 292 inches^2.
