Option (3).
R intersects K at SB.
Correct.
Since line of intersection of planes R and K is SB
Option (4)

Incorrect.
Angle between them is not 90°.
8x - 6 > 12 + 2x
8x - 2x > 12 + 6
6x > 18
x > 18/6
x > 3........so the solution set contains numbers greater then 3....and not including 3....so 4,5,6,7...and so on
Answer:
both angles are the same, so you can use it interchangeably in proving.
But i suggest you to mantain only one, because it's easier to understand and it looks better.

Answer:
18 3/4
Step-by-step explanation: You would simply subtract 26 5/8 - 7 7/8. You would have to make 26 5/8 into an improper fraction 25 13/8 and subtract that by 7 7/8 to equal 18 6/8 which you would then simplify into 18 3/4.
