Answer:
Step-by-step explanation:
We are to show that
<u>Proof:</u>
From trigonometry identity;
From trigonometry, 2sinAcosA = Sin2A
Also note that sin(B-C) = sinBcosC - cosBsinC
sin420cos140 - cos420sin140 = sin(420-140)
The resulting equation becomes;
=
He had 28.5kg but then he sold 16.93kg so that would be 28.5kg - 16.93kg which is 12.57kg, and then he sold another 9.807 so you do 12.57 - 9.807 which is 2.763kg. Are you sure this is middle school maths and not primary school?
