Answer:
Postulate.
Step-by-step explanation:
If two distinct planes intersect, then their intersection is a line. This is a postulate.
A postulate is a true statement, which does not require to be proved.Postulate is used to derive the other logical statements to solve a problem.
Postulates are also called as axioms. Postulates are the basic structure from which lemmas and theorems are derived. Postulates are the most basic assumptions with which a reasonable person would agree.
Prime Factors of 60: 2,3, and 5
Prime Factors of 140: 2,5 and 7
All mental math no work needed.
Answer:
20
Step-by-step explanation:
because angle 5 is found on the same line as 45 degrees (don't remember what that's called), we can subtract from 180 to find
angle 5 = 135
angle 5 and 5x+35 are alternate interior angles, so they have the same value
135=5x+35
100=5x
20=x
Answer:
12 hours of work
Step-by-step explanation:
$128 ---------> 8 hours of work
$1 -------------> (8/128 ) hours of work
$192 ----------> (8/128 ) x 192 = 12 hours of work
