Answer:

79 sociology textbooks and 138 biology textbooks

Step-by-step explanation:

Create a system of equations, where b is the number of biology books and s is the number of sociology books:

b + s = 217

b = s + 59

Solve by substitution by substituting s + 59 for b into the first equation:

b + s = 217

s + 59 + s = 217

Add like terms and solve for s:

2s = 158

s = 79

So, there were 79 sociology books. To find the number of biology books, substitute 79 in for s into the equation b = s + 59

b = s + 59

b = 79 + 59

b = 138

So, 79 sociology textbooks and 138 biology textbooks were sold.

Lines a and b are parallel. What is the measuee of angle S?
WITCHER [35]

Answer:

The measure of angle s is 22°

Step-by-step explanation:

Given:

  • Horizontal lines A and B are parallel and are intersecting because a line is going through the both of them.
  • Top right angle of line A is labeled to be 158°, while the top left angle in line B is labeled S° indicating this variable is the missing degrees.

To find:

  • The angle of S, in degrees.

∠1 and 158° are both on a straight line and supplementary.

(Supplementary angles are those angles that sum up to 180 degrees. )

So solving,

⇒ ∠1=180°-158°=22°         ....> Angles ∠1 and S are interior angles

Due to lines A and B being parallel, all interior lines are equal.

As a result, the answer is therefore 22°.
