Answer:
No solution
Step-by-step explanation:

Lets consider the equation 2.
Here we multiply the LHS and RHS with (-1).

Hence,

When we add the equations we get,

As 0 doesn't equal to -1, answer is d) No solution
Answer:
1000 gallons of tank
Step-by-step explanation:
Answer:
We have sin² x + cos² x =1 for all real x.
Therefore, sin² x = 1 – cos² x = 1 – (8/17)² = 1 – 64/289 = 225/289 = (15/17)².
However, remember that if x² = a², then x can be +a or –a.
Therefore, sin x can be either –15/17 or +15/17.
Everyone but Anirban so far has forgotten the negative solution.
Step-by-step explanation:
Given that sinθ=817 and cosθ<0 , we have: cosθ=−√1−sin2θ. cosθ=−√1−(817)2. cosθ=−√1−64289.
Answer:
8/15
Step-by-step explanation:
KCF (Keep, Change, Flip)
keep 2/5, change ÷ to ×, flip 3/4 to 4/3
2/5 × 4/3
2×4=8
5×3=15
8/15
Hope it helps :)
You could use sine to find it
sin45 = 8/m
m = 8/sin45
