Answer:
First let's define what modular arithmetic is, what would come is an arithmetic system for equivalence classes of whole numbers called congruence classes.
Now, the modular division is the division in modular arithmetic.
Answering the question, a modular division problem like ordinary arithmetic is not used, division by 0 is undefined. For example, 6/0 is not allowed. In modular arithmetic, not only 6/0 is not allowed, but 6/12 under module 6 is also not allowed. The reason is that 12 is congruent with 0 when the module is 6.

Matt's steps will be more complicated since Annie is using a program to do the constructions hers would probably be precise and easy.
Answer:
x= 120
Step-by-step explanation:
x+60=180
x=180-60
x=120
Answer:
<h2>
11.4</h2>
Solution,
∆ ACB = ∆ EFD
finding the value of X,

Apply cross product property

Calculate the product

Divide both sides by 5

Calculate
