3∅ can be rewritten as (2∅+∅)
sin(3∅) = sin(2∅ + ∅<span>)
Opening brackets on the right hand side;
= sin2</span>∅ cos ∅ + cos2∅sin<span>∅
</span><span>This simplifies to;
= 2sin</span>∅cos^2∅ + sin∅ (1- 2sin^2∅<span>)
= sin</span>∅ (2cos^2∅ + 1 - 2sin^2∅<span>)
= sin</span>∅ (2(1 - sin^2∅) +1-2sin^2∅<span>)
= 3sin</span>∅ - 4sin^3<span>∅</span>
Answer: p = - 5.8
Step-by-step explanation:
0.7p - 0.2p = -9.57 + 6.67
0.5p = -2.9
p = 
p = - 5.8

You would divide £52.65 by 27 to find out what 1 packet costs, thus leads us to £1.95. Then you would do £1.95 x 35 as there are 35 packets to get the answer £68.25
