Start with the lowest prime number: 2
is 84 divisible by 2? Yes
so. 84/2 = 42
Check if it still divisible by 2,
yes, 42/2 = 21
check if it is still divisible by 2,
no, move to next prime number = 3.
check if it is divisible by 3
yes, 21/3 = 7.
now since, 7 is a prime number, we stop.
and the prime factors of 84 are : 2,2, 3, 7
4 prime factors, 3 distinct.

Answer:
x = 120°
Step-by-step explanation:
In order to find the value of x, first you need to find the values for each angle in ΔQTS. ∠QTS is equal to 70°. In order to find ∠QST we need to do 180 - 50 - 70 = 60°. Because we know that ∠QST is 60°, we can do 180 - 60 to find x, and we get 120°
