the 3 angles need to equal 180 degrees.

Add them together:

42 + 5x + 7x +6 = 180

Combine like terms:

12X + 48 = 180

Subtract 48 from each side:

12X = 132

Divide both sides by 12:

X = 132 / 12

X = 11

Now replace x with 11 and solve CBE:

CBE = 7X + 6

7(11) + 6

77 + 6

CBE = 83 degrees

I<br> 8. Classify 8 as a perfect square, a perfect cube, both, or neither.

Murljashka [212]

Answer:

It's a perfect cube, but not a perfect square.

Step-by-step explanation:

2^3 = 8, meaning 8 is a perfect cube. But since 2^2 = 4 and 3^2 = 9, and 8 is in between, 8 is not a perfect square.

I hope this helped.
