Option B. 13π/6 and Option D. 5π/6
To get the reference angle π/6 for the given angles we will check each angle given in the options.
A. 8π/6
Since 8π/6 means 240° which lies in 3rd quadrant. Therefore reference angle of 240°= 240-180 = 60° or π/3
B. 13π/6
13π/6 means 390° which lies in first quadrant.
Therefore reference angle = 390-360 = 30° or π/6
C. 3π/6
Since 3π/6 means 90° therefore reference angle of 90° is the same as 90°.
Or the reference angle is = π/2
D. 5π/6
5π/6 means angle is 150° which lies in second quadrant therefore reference angle of 150° = 180-150 = 30° or π/6
answer is Option B and D.
Answer:The Last One
Step-by-step explanation:
480 stickers on 6 sheets is greater because 480 divided by 6 is 80, whole 120 divided by 2 is 60
Answer:
A). 
B). 
Step-by-step explanation:
A). 
To get the square root of the given expression we will convert it into the square form.
[Since 2×2 = 4 and 
]
Therefore, 
B). 
Since, 
Therefore, 
[Since 3² = 9 and (m⁷)² = m¹⁴]
Answer:
x = 16
Step-by-step explanation:
x
-- = 9-1 ...... first shift 1 and it will be -1
2
x = 8 ....... secondly 9-1 =8
--
2
x = 16 ..... criss cross and 2×8 = 16
there fore the value of x is equals to 16.
you can check it!
