Answer:
b. mutually exclusive.
Step-by-step explanation:
The given description is an illustration of mutually exclusive events.
Take for instance, when you roll a die;
It is impossible to have an outcome of 2 and 6 at the same time; these means that 2 and 6 are mutually exclusive.
In a nutshell, when two or more sates of events/states of nature can not happen at the same time; such events/states of nature are mutually exclusive.
Answer:
x = 1
Step-by-step explanation:
Since, angle TUV has been divided in two parts by a ray UW
Measure of angle TUV = measure of angle TUW + measure of angle WUV
m∠TUV = m∠TUW + m∠WUV
By substituting the values of the given angles,
(9x + 1) = (7x - 9) + (5x - 11)
9x + 1 = 12x - 20
12x - 9x = 20 + 1
21x = 21
x = 1
Therefore, x = 1 will be the answer.
