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.
Answer:

Step-by-step explanation:
(w circle r) (x) is the composite function(w of r(x)), that is, w(r(x))[/tex]
We have that:


Composite function:

is a negative parabola with vertex at the original.
So the range(the values that y assumes), is:

Answer:
y= -3x +6
Step-by-step explanation:
Just graph it I guess
Answer: {3, 5, 7}
---------------------------------------
---------------------------------------
The range is the set of outputs of a relation or function. In other words, it's the set of possible y values. Recall that ordered pairs are of the form (x,y) so the y coordinate is listed after the x. The output is listed after the input. The output values are y = 3, y = 3, y = 3, y = 5, y = 7. So we simply list these outputs without the "y=" portion. Toss out any duplicates. Only write the unique output values.
The curly braces surrounding the list of values tells us that we have a set.
Answer:

Step-by-step explanation:
• Let's first find Angle ACB

• From alternative angles, x = Angle BAC.
• Since AB = AC, then Angle ABC = Angle ACB
