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

Given the equation 5 + x - 12 = x - 7.
Anuta_ua [19.1K]

Answer:

part A=    x=1

part B=   -13=-11 and -7=-7 and -2=-2

Step-by-step explanation:

part A

5+x-12=x-7

-7+x=x-7

x=1

part B

5+(-4)-12=-4-7

-1-12=-4-7

-13=-4-7

-13=-11

5+x-12=x-7

5+(-12)=-7

-7=-7

5+x-12=x-7

5+5-12=5-7

10-12=-2

-2=-2

explain why multiplying the numerator and the denominator of a fraction by the same number results in an equivalent fraction.​
alisha [4.7K]

Answer:

We also know that when you have the same numerator and denominator in a fraction, it always equals 1. For example: So as long as we multiply or divide both the top and the bottom of a fraction by the same number, it's just the same as multiplying or dividing by 1 and we won't change the value of the fraction.

Brooke found the equation of the line passing through the points (–7, 25) and (–4, 13) in slope-intercept form as follows.
Arturiano [62]

For this case we have that by definition, the equation of a line in the slope-intersection form is given by:

y = mx + b

Where:

m: It's the slope

b: It is the cut-off point with the y axis

m = \frac {y2-y1} {x2-x1}

We have the following points:

(x1, y1): (- 7,25)\\(x2, y2): (- 4,13)

Substituting the values:m = \frac {13-25} {- 4 - (- 7)} = \frac {-12} {- 4 + 7} = \frac {-12} {3} = - 4

Thus, the line is of the form:

y = -4x + b

We substitute one of the points and find "b":

13 = -4 (-4) + b\\13 = 16 + b\\b = 13-16 = -3

Finally we have to:

y = -4x-3

Answer:

The equation es y = -4x-3
