THEOREM:

  • Supplementary angle —: Two angles are called supplementary when their measures add up to 180 degrees.

ANSWER:

By supplementary angle theorem,

  • m∠ABC + m∠QRS = 180°
  • 100° + m∠QRS = 180°
  • m∠QRS = 180° – 100°
  • m∠QRS = 80°

Hence, the measure of m∠QRS is 80°.

Marley had $120 to buy books. She purchased 6 books and has $18 left.<br> How much was each book?
Hatshy [7]

Answer:

$17

Step-by-step explanation:

If Marley had $120 to buy books and has a remainder of $18 left, then you would subtract 18 from 120 first.

120 - 18 = 102

Next you would divide.

102/6 = 17

The price of each book was $17.
