Answer:

  70° (number in the blank at the bottom)

Step-by-step explanation:

You need to know the meaning of "complement of an angle."

Complementary angles have a sum of 90°. So, the complement of 20° is the angle that makes the total 90°. It is 70°.

The line at the bottom of the figure tells you how to work the problem. It says "the cosine of an angle is the sine of its complement." If you put numbers in this statement, it tells you ...

  the cosine of 20° is the sine of 70°

So, the answer to the question at the top of the page is ...

  look up the value of sin(70°) in the table

Set y= 22x+4 and y= 14x+28 equal and solve algebraically
Doss [256]

Answer:

x = 3; y = 70.

Step-by-step explanation:

When you set the two equations equal to each other you get:

22x + 4 = 14x + 28

This is a multi-step equation since the variable is on both sides of the equal sign.  In order to solve any equation, you must use inverse (opposite) operations to isolate the variable and whatever you do to one side of the equal sign, you must do to the other.  The first step for this equation is to get the variable on one side and the constants on the other.  Subtracting 14x from both sides:  22x - 14x + 4= 14x - 14x +28 gives us 8x +4 = 28.  Next, subtract the 4 from both sides to get:  8x +4 - 4 = 28 - 4 or 8x = 24.  Lastly, divide both sides by 8 to get x = 3.  To solve for y, simply plug 3 in for 'x' in either of the initial equations:  y = (22)(3) + 4 = 70.
