Answer:
5x+60 = 360, x = 60
Step-by-step explanation:
Ok, so the key to this problem is to realize that all angles added up in a quadrilateral give you 360 degrees. This means that x+10 + 2x + 2x + 50 = 360. Then we can just simplify to 5x + 60 = 360, 5x = 300, and x = 60.
Answer:
P(odd number) = 0.5
Step-by-step explanation:
There are 90 members in the set (10, 11, 12, .. , 97, 98, 99)
When we have an even number of consecutive numbers, the number of even numbers equals the number of odd numbers. This means that half of the numbers in this set are even and half of them are odd.
So the probability of P(odd number) = 0.5
The answer to the question is 5
