Sin x = cos (90-x)

eg sin 42 = cos(90-42) = cos 48

so the answer is B

Answer:

The correct answer is option B, 42;48

Step-by-step explanation:

The congruent angles are complementary to each other and thus their sum shall be equal to 90 degrees

$sin x = cos (90-x)\\$

Let put x = 42 degrees in the equation, we get -

$sin 42 = cos(90-42) = cos 48\\$

Thus the congruent values for sin x and Cos Y is 42, 48

If m<1 = 38 then m<4 =

Mariana [72]

Answer:

If m<1 = 38 then m<4 = 38

Step-by-step explanation:

Both of the angles equal 38 degrees. This is true because the angles are vertical, vertical angles are angles opposite each other where two lines cross. Vertical angles are also always congruent, therefore the m<4=38.

What function equation is represented by the graph?

Ahat [919]

In the given graph, lets mark two points:

Let $A = (0,-3)$ and $B = (4,-2)$

The slope of the line is given by:

$m = \frac{(-2)-(-3)}{(4)-(0)}$

$m = \frac{-2+3}{4}$

$m = \frac{1}{4}$

The equation of the line is given by:

$(y-y_1)=m(x-x_1)$

$(y-(-3))=(\frac{1}{4})(x-0)$

$4(y+3)=x$

$4y+12=x$

$4y=x-12$

$y= \frac{1}{4}x-3$

Therefore, the function equation represented by the graph is: $f(x)= \frac{1}{4}x-3$

True or false: two points with the same x-coordinate are always on the same vertical line

Vesna [10]

True, you can even test it out yourself. If the domain (x) is the same then it will be a vertical line. Like if you graphed (1,2) (1,4), (1,6) it will be a vertical line on your graph. I hope this helps!
