Sin J = cos K
sin J = cos (90 - J)
K = 90 - J
sin 60 = cos (90 - 60) = cos 30
Therefore, 60°, 30° satisfy the condition sin J = cos K.
Cosine is probably either opp/hyp or adj/hyp
-2x^2 + 11x - 4
To get this answer, you need to combine like terms. However, before this, remember that you are ADDING, so don’t accidentally subtract any numbers.
Then, just follow these steps:
2x^2 + (-4x^2) = -2x^2
5x + 6x = 11x
-7 + 3 = -4
And proceed to put them in the equation correctly.
Hope this helps!
