Step-by-step explanation:

Let the width of the mechanical pencil lead be w_m and the width of a human hair be w_h. We are trying to find the number of widths of pieces of hair (let that be n) that make it equal to the width of a mechanical pencil lead, so we write the equation w_m=n*w_h. Hopefully, writing an equation makes this easier to understand!

Now, I want n, so I divide be w_h on both sides, substitute, and get that n = w_m/w_h = (7*10^-4)/(1*10^-4)

The 10^-4’s cancel, so we get n = 7/1 = 7.

I hope this helps! :)

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.

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
