Given the three sides of a triangle, classify the triangle as acute, right, or obtuse.
11, 7, 4
A. acute
B. right
C. obtuse

acute

Step-by-step explanation:

Given the 3 sides of a triangle a, b, c ( where c is the longest )

• If a² + b² = c² ⇒ right triangle

• If a² + b² > c² ⇒ acute angled triangle

• If a² + b² < c² ⇒ obtuse angled triangle

Here a = , b = , c = 4

c² = 4² = 16

a² + b² = ( )² + ( )² = 11 + 7 = 18

Since a² + b² > c² then triangle is acute

$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
