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:
P = 5.3x = 206,700
Step-by-step explanation:
P = population
P = 5.3x, where x is the square miles
p = 5.3(39000) = 206,700
It's a right triangle as it has the 90 degree corner and 3 different lengths
Answer:
D)
Step-by-step explanation:
Because
a) 10 = 2(5) = 10
b) 10 = 5 + 5 = 10
c) 10 = 15 -5 = 10
d) 10 = 5 - 5 = 0 the result is not equivalent
