Answer:
229.2
Step-by-step explanation:
Remark
There's a lot in this question. The x is not just any x. It is defined and limited by its relationship with the sine function.
The Sin is defined as Opposite over Hypotenuse in a right triangle. The 670 is the Hypotenuse. You know that by the definition of Sine.
So one thing you should always keep in mind: the x because of where it is in the definition, will always be smaller than the Hypotenuse. So you should get a value less than 670.
Formula
Just as you have it
Sin(20) = x / 670
Solution
Multiply both sides by 570
670 * sin(20) = x
sin(20) = 0.3420
x = 670 * 0.3420
x = 229.2
Answer:
-8
Step-by-step explanation:
3+8+8-2=17
7+4+5+1=17
10+12+3+x=17
x=17-25
=-8
The answer would be 1/3. You have to work backwarda for this problem. You start off by subtracting 5/4 - 3/4 =2/4 which simplifies to 1/2. Then, you have to add 1/6. Using the greatest common denominator, you have 3/6 + 1/6=4/6 which simplifies to 2/3.
