Answer: To determine to measure of the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2.
Step-by-step explanation:
Answer:
Domain: 
Step-by-step explanation:
Given
Required
Determine f(x) and its domain
To determine f(x), we replace 5x with x in f(5x)
So, we have:
Take LCM
To get the domain, we set the denominator as
Since it is in between 3.1 and 3.2, and you are saying that it has 2 decimal places, then it could be the following numbers (choose any 2 of these you want): 3.11; 3.12; 3.13; 3.14; 3.15; 3.16; 3.17; 3.18; 3.19.
