Answer:
x = 10
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin60° = 
, then
sin60° = 
= 
= ( cross- multiply )
2x = 20 ( divide both sides by 2 )
x = 10
Answer:
yes razi is correct pateran 3
Step-by-step explanation:
Since the argument of the sine function is x without any scaling factor, the period is 2π, the 1st selection.
Answer:
9/8
Step-by-step explanation:
the quotient of -3/8 and -1/3
= (-3/8) / (-1/3)
= (-3/8) x (-3/1)
= 9/8
First you have to solve both inequalities,
3x-1>8
3x>9
x>3
and the other one
2x≤4
x≤2
then you graph each one on the number line
the graph says or, so the solution can satisfy either equation
the solution would be all real numbers except three
the way to write it is x≠3
