Joel uses a claw hammer to remove a nail from a wall. he applies a force of 40 newtons on the hammer. the hammer applies a force of 160 newtons on the nail. the mechanical advantage of the hammer is blank

The mechanical advantage of the hammer is 4.

Step-by-step explanation:

We know that the mechanical advantage of the hammer is is given by the ratio between the force applied on the hammer and the force required to overcome the given force.

Force applied = 40 N

Force required= 160 N

Mechanical advantage =

Mechanical advantage =

Hence, the mechanical advantage of the hammer is 4.

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
