When a pair of parallel lines is intersected by a transversal, then
Interior opposite angles are equal.
So, (3x + 4)° = 115°
=> 3x + 4 = 115
=> 3x = 115 - 4
=> 3x = 111
=> x = 111/3
=> x = 37
Answer:
1497
Step-by-step explanation:
When finding the average you add all the given numbers
623+494+380=499
Then divide that answer by how many total numbers are there
499*3=1497
Answer:
5000
Step-by-step explanation:
in order to find how many revolutions, you need to find the circumference of the circle which is 2pi r.
thus, you will get this working out:
circum= 2 times 22/7 times 14
= 88cm
4.4 km = 440000cm
Then, 440000cm divide 88 cm =5000.
Thus, 5000 revolutions.
