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.
a=2, b=3
Then just substitute in a and b.
Hope I helped, I've had this problem before!

The answer is (C). All sides and angles of the square is equal. Its diagonals bisect each other and meet at 90°. If two lines are said to meet at 90°, these lines are perpendicular to each other. Therefore, the diagonals of a square is perpendicular to each other
Answer:
f(x) = 3x2 + 5 and y = 3x2 + 5
Step-by-step explanation:
The expressions that follow f(x) = and y = are the same, so these are two different ways to write the same function: f(x) = 3x2 + 5 and y = 3x2 + 5.
B. 60 Alternate angles are equal
