Sin x  = cos (90-x)

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

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

5. When looking at a map, a student realizes that Birmingham is nearly due west of Atlanta, and Nashville is nearly due north of
leonid [27]

Answer: 250 mi

Step-by-step explanation:

Here we can think in a triangle rectangle:

The distance from Birmingham to Atlanta is roughly 150 mi, and this is one of the cathetus.

And the distance from Birmingham to Nashville is roughly 200 mi, this is the other cathetus of the triangle.

Now, the distance from Atlanta to Nashville will be the hypotenuse of this triangle rectangle.

Now we can apply the Pythagorean's theorem:

A^2 + B^2 = H^2

Where A and B are the cathetus, and H is the hypotenuse:

Then:

H = √(A^2 + B^2)

H = √(150^2 + 200^2) mi = √(62,500) mi = 250 mi

Then the estimated distance from Atlanta to Nashville is 250 mi

<u>Answer:</u>

  • 17.5 ft.²

<u>Step-by-step explanation:</u>

  • Surface area: 2(4 x 0.5) + 2(4 x 1.5) + 2(0.5 x 1.5)
  • => 2(2) + 2(6) + 2(0.75)
  • => 4 + 12 + 1.5
  • => 17.5 ft.²

<u>Conclusion: </u>

Therefore, the surface area is 17.5 ft.².
