Martin is making a model of a Native American canoe. He has 13 1 2 feet of wood. He uses 6 3 4 feet for the hull and 5 1 4 feet for a paddle. How much wood does he have left?

1 1/2 feets

Step-by-step explanation:

Given that :

Total amount of wood = 13 1/2 feets

Amount of wood used for hull = 6 3/4 feets

Amount used for paddle = 5 1/4 feets

Total amount of woods used :

(amount used for hull + amount used for paddle)

(6 3/4 + 5 1/4) feets

6 + 5 + (3/4 + 1/4)

11 + 4/4

11 + 1

= 12 feets

Amount of wood left :

Total amount of woods - total amount used

13 1/2 feets - 12 Feets

= 1 1/2 feets

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
