If sinxcos(pi/7)-sin(pi/7)cosx=-sqrt2/2 then x can equal?
2 answers:
I'm going for a range of 0 < x <2<span>π
This is R sin (x-a), although R is 1.
a = </span><span>π/7, so
=> sin (x-(</span><span>π/7)) = -1/(sqrt(2))
=> x = 53</span>π/28, 39<span>π/28</span>
Answer:
its's 5pi/4 +pi/7 and 3pi/4+pi/7

Answer/Step-by-step explanation:
Recall: SOH CAH TOA
✔️Sin D = Opp/Hyp
Opposite = 7
Hypotenuse = 25
Substitute:
Sin D = 7/25
m<D = 16.3°
✔️Cos F = Adj/Hyp
Adjacent = 7
Hypotenuse = 25
Substitute:
Cos F = 7/25
m<D = 73.7°
Answer is <span>b. 121/27
</span><span>3+1+1/3+1/9+1/27
= </span><span>3+1+9/27+3/27+1/27
= 4 13/27
= 121/27</span>
