square root(-108) - square root(-3) =8.66025404 i
Answer:
Step-by-step explanation:
<u>As per the diagram we got:</u>
<u>As FH = 7x + 4 and EH = 9x - 2, we solve the following equation for x:</u>
- 7x + 4 = 9x - 2
- 9x - 7x = 4 + 2
- 2x = 6
- x = 3
<u>So each segment is:</u>
<u>Therefore</u>:
<u>So the variables are:</u>

cos (arctan (1))=
arctan (1) = 45 take it to the third quadrant = add 180 = 225
cos (225) = -1 / sqrt(2)
never leave a sqrt in the denominator
= -1 /sqrt(2) * sqrt(2)/sqrt(2)
= -sqrt(2)/2
sin (arccos (1/2)
arccos (1/2) = 60 take it to the 4th quadrant -60 degrees
sin (-60)
- sin 60
- sqrt(3)/2
