If sin theta = 1/2, which could not be the value of theta? a. 30 b. 210 c. 150 d. 390 this was a repost.

B

Step-by-step explanation:

since sin Θ > 0 then Θ is in first/ second quadrants

210 is in the third quadrant and not a solution

30 is in the first quadrant and is a solution

150 is in the second quadrant and is a solution

390 is in the first quadrant (390 - 360 ) = 30 and is a solution

english, cause i can’t you

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
