15.75=5(1+i)^2
3.15=1+i^2
2.15=i^2
i= √2.15 or approximately 1.47
So 4a=0.24 well its simple
your gonna divide 4 on both sides the 4 crosses out and 0.24 divided by 4 equals 0.06 or just .06 does that make sense?
SIn J = 10sin102/17 = 0.575
arcsin 0.575 = 35.1 = 35 degrees
Answer:
Sine Formula or Sine Rule :
BC / sinA = AC / sinB
60 / sinA = 84.95 / sin(115°)
60 / sinA = 84.95 / 0.91
60 / sinA = 93.7
sinA = 60 / 93.7
sinA = 0.64
A = arc(sin0.64)
A = 39°48'30"
A ≈ 40°
Hence, the value of angle BAC is <u>40°</u>
- <u>40°</u> is the right answer.
Not at alll . Multiply by 5 and you wouldnt get 5/25
