The perimeter of ΔHAT is 110. HA = x + 5, AT = 2x – 25, and HT 40. Is ΔHAT scalene, isosceles, or equilateral?

x + 5 + 2x – 25 + 40 = 110

3x + 20 = 110

3x = 90

x = 30

The sides are 40, 35 and 35, so isosceles.

slide10

The perimeter of ΔAND is 69. AN = 23, ND = 3x + 2 and DA = 5x - 12 Is ΔAND scalene, isosceles, or equilateral?

23 + 3x + 2 + 5x – 12 = 69

8x +13 = 69

8x = 56

x = 7

The sides are 23, 23, and 23 so equilateral.

The perimeter of ΔBUG is 36. BU = 12, BG = 2x + 2, and UG = 3x – 3. Is ΔBUG scalene, isosceles, or equilateral?

12 + 2x + 2 + 3x – 3 = 36

5x + 11 = 36

5x = 25

x = 5

The sides are 12, 12, and 12, so equilateral
