It's a complimentary angle.

Complimentary angles both add up to 90 degrees, as you can also tell by the square with indicates a 90 degree angle.

Make (x + 54) + 5x = 90.

x + 54 + 5x = 90

Add like terms.

6x + 54 = 90

Subtract the 54.

6x = 36

Divide by 6.

x = 6

5x+x+54=90. They are complementary angles so they added up to 90 degrees. This simplifies to 6x=36, then simplifies more to x=6. So, x=6.

1. - Since a cube is all the same lengths on all sides you would want to find the area of one of the sides. You would do this by multiplying 3.8 by 3.8.
3.8*3.8=14.44
Since you have six faces on a cube you want to multiply this by 6.
14.44*6=86.64
So your answer for 1. is 86.64 in^2 of glass

3. Same thing as number one. Find the face of one side:
1 1/3*1 1/3 is about 1.7777
Multiply this by the six faces. 
1.7777*6 is about 10.66666
So your answer for 3. is about 10.666 (repeating) in^2

4. For this one, you want to follow the surface area formula for a cylinder. Which is - A=2πrh+2πr^2
When you put all your numbers in it would look like this: 
2*3.14*2*22+2*3.14*2^2
Once you do that equation you will get 301.44
So that should be your answer 301.44 cm^2

Hope this helps!
