Answer:
Step-by-step explanation:
first of all arrange this data from ascending to descending order.
11,15,15,15,16,17,18,19,20,22,23
use formula
N+1/4 (N means no of observations)
11+1/4
12/4
3 rd term
therefore Q1=15
6t - 20 - 32u
6(6) - 20 - 32(1/4)
36 - 20 - 8
36 - 20 = 16 - 8 ⇒8
The final answer is 8.
8x +6° +118° = 180° ( linear pair)
=> 8x = 180°-124°
=> 8x = 56°
=> x = 7°
hope this helps you.
I am pretty sure its the first one
