  obtuse

Step-by-step explanation:

If the triangle were a right triangle, the longest side would be found using the Pythagorean theorem:

  a² + b² = c²

  4.5² + 6² = c² = 20.25 +36 = 56.25

  c = √56.25 = 7.5

At 8.5 cm, the longest side is longer than that necessary to make a right triangle, so the largest angle is greater than 90°.

Stephanie's triangle is an obtuse triangle.

$450.00 for 6 weeks

or

$300

step-by-step explanation:

$200.00 for first week $50.00 x5 equals $250 plus $200 equals $450.00 for six weeks.

$200 for first week

$200 x 0.10 = $20

$20 x 5 = $100

$200 + $100 = $300
