Can someone help me with the questions in the picture?

13) Scalene

14) Iscosceles

15) Right

16) Scalene

17) Iscosceles

18) Right

Pretty simple explanations:

Iscosceles: 2 sides equal 1 side not, 2 angles congruent

Scalene: all sides and angles not congruent

Right: has a right angle in its legs

the answer is 15.50 for one mile

b) is slope: 0   y- intercept 15.5

look at the picture.

1.

ef : ab = 2 : 3

gf : cb = 2 : 3

gh : cd = 2 : 3

he : da = 2 : 3

2.

∠a ≅ ∠e

∠b ≅ ∠f

∠c ≅ ∠g

∠d ≅ ∠h

3.

use pythagorean theorem:

the length of the abcd trapezoid sides:

|ab| = 3 cm

|bc| = 10 cm

|cd| = 3(3) cm = 9 cm

|da| = 8 cm

the perimeter of abcd = 3 + 10 + 9 + 8 = 30 cm

the ratio of perimeters of the tarapezoids is equal 2 : 3.

substitute:

      cross multiply

      divide both sides by 3
