Answer:
x=-5
Step-by-step explanation:
opening the bracket on the LHS, we have
-8x-40= -3x+x-7-3
-8x-40= -2x-10
collecting like terms
-8x+2x= -10+40
-6x= 30
divide both sides by -6
x= -5
Step-by-step explanation:
sinx=20/36
x=sin-¹20/36
x=34
It would be 56 seconds until both flicker at the same time
have a happy day :)
