lina2011 [118]

Answer:

Step-by-step explanation:

The two triangles are similar by AA

Firstly, we can see that angle LKM and QKR are congruent as they are vertical angles.

The second set can be identified by noticing that RM is a transversal through 2 parrallel lines LM and QR. That manes QRK, and LMK alternate interior angles, showing that the angles are congruent. Hence similarity by AA

an electrician has 4.1 meters of wire. How much stripes 7/10m long can he cut? How much wire will he have left over?
ratelena [41]

Answer:

5 such strips of \frac{7}{10}\ m can be cut and \frac{6}{10}\ m  would be left over.

Step-by-step explanation:

Given is4.1= \frac{41}{10}\ m length of a wire.

We have to cut strips of \frac{7}{10}\ m

If we factorize 41 \ by \ 7

We get 5 full and and \frac{6}{7}

Similarly , if we factorize \frac{41}{10} \ by \ \frac{7}{10}

We get full 5 \ strips and another \frac{6}{10} \ m would be left.
