Isolate the variable by dividing each side by factors that don't contain the variable.
x = 1
-6+3x+4=2-4x+3
-8+7x+1=0
7x=7
x=1
Answer:
This may not be that accurate as I am a bit rusty with trigonometry:
tan D: d/f
sin F: f/e
tan F: f/d
cos F: d/e
sin D: d/e
cos D: f/e
As we know that :
so, over here
plugging the value of i² as -1
