The value of x given that the sum of exterior angle is 360 is 27
<h3 /><h3>Sum of exterior angle of a pentagon </h3>
Sum of exterior angle of a pentagon is 360°. Taking the sum of the angles and equating to 360 degrees, we will have:
2x - 20 + 2x + 50 + 3x + 10 + 3x + 50 = 360
Collect the like terms
10x + 90 = 360
Subtract 90 from both sides
10x + 90 - 90 = 360 - 90
10x = 270
x = 27
Hence the value of x given that the sum of exterior angle is 360 is 27

Answer:
Option C
Step-by-step explanation:
same logic as in 2D problems. if C wasn't true, then the two planes couldn't be parallel
Jessi work is correct. Everyone did the work correctly as far as the method but only Jessi’s work was correct because 6/12 = 1/2
YOUR ANNSWER IS B OR JESSI’S WORK.
Assuming There is ONLY ONE CORRECT ANSWER,
The probability of her guessing the answer without ruling out the choices is 1/5.
if 3 choices are ruled out, then 1 out of the remaining two is right, which gives the probability 1/2
now, 1/5 = 20% , while 1/2 = 50%.
Therefore her probability of getting the correct answer improves by 30% [ not much in a REAL test though :P ]
