Answer:
Step-by-step explanation:
cosine law
a²=b²+c²-2(bc)cos44 (c=20, b=15)
a²=15²+20²-2(15*20)cos44
a=√15²+20²-2(15*20)cos44
a=13.91
1% would be £60
3% would be £180
0.5% would be £30
3.5% would be £210
103.5% would be £6210
Answer:
ab and cd intersect at E because they are vertically opposite angles they always intersect at a point
Answer:
21.04
Step-by-step explanation:
