Answer:
x = 3, 4, 5
Step-by-step explanation:
Solving the inequality
5x + 2 > 12 ( subtract 2 from both sides )
5x > 10 ( divide both sides by 5 )
x > 2
Thus the only values from the given set which make the inequality true are
x = 3, 4, 5
X = 61 degrees.
Find the number of degrees in a pentagon by using the following formula:
(number of sides - 2)180 = 540.
There are 540 degrees in a pentagon.
Since we know four of the angles, we can subtract them from 540 to get the fifth angle.
540-138-144-107-90 = 61
Hope this helped =)
