Dividing the parallelogram in half and applying trigonometry is the easiest solution for me.
<u> 4 x² = 64</u>
Divide each side by 4 : x² = 16
Take the square root
of each side: x = √16
x = <em>+ 4</em>
and
x = <em>- 4</em> .
Answer:
Step-by-step explanation:
n(30/100)=27
n=100(27)/30
n=90
sin(
)=Sin(
-0) =Sin 0=0
