Riddle-if you solve it i will delete your answer and you have to post the riddle. Riddle-you enter a room. 2 dogs, 4 horses, 1 g
My name is Ann [436]

Considering the number of legs of each animal, it is found that there are 56 legs on the ground.

<h3>How many legs does each animal have?</h3>

  • Dogs have 4 legs.
  • Horses have 9 legs.
  • Giraffes have 4 legs.
  • Ducks have 2 legs.
  • Chickens have 2 legs.

Hence the number of legs on the ground is given by:

N = 2 x 4 + 4 x 9 + 1 x 4 + 1 x 2 + 3 x 2 = 56.

A similar problem, also involving the number of legs of each animal, is given at brainly.com/question/14010151

Analyze the diagram below and answer the question that follows.
butalik [34]
M/IGJ will equal 52 degrees.
Since EGF is 90 degrees then and EGD equals 38 degrees you need to subtract 38 from 90 and you are left with 52 degrees for angle FGD. The alternate interior angle to FGD is IGJ which would make the angles congruent.
