Answer: Angles who share the same initial side and terminal sides.
Answer:
a = 15
Step-by-step explanation:
Substitute b = 12 , a = 9 into the equation
12 = 
12 = 
← square both sides
144 = a² - 81 ( add 81 to both sides )
225 = a² ( take square root of both sides )
± 
= a , then
a = ± 15
a > 0 , so a = 15
1+2 that what it is im juts joking idek how to solve that
<span>If 75% of the students had taken 8 courses, 25% had not. Of these remaining 25%, 60% of them (or 60% of 25% = 15%) had taken 6 or 7 courses. Thus 90% (75% + 15%) of the students had taken 6, 7 or 8 courses.
Thus only 10% had taken less than 6 courses. I hope this helps.
