This is short cut for this type of questions, ie, gain or loss square/100=5^2/100=>0.25%loss
Always this type of questions will have loss
Answer:
Step-by-step explanation:
Given that When n is divided by 21, the remainder is an odd number.
i.e.
where m is an integer and k a positive integer <21
When n is divided by 28, the remainder is 3
, where c is a positive integer
This can be written as

Since n is giving odd remainder when divided by 21,
we get r =3 as n is a multiple of 7 +3

9x-8 is the simplified form
Answer:
The measure of the third angle is 75 degrees.
Step-by-step explanation:
We know that the total angles of a triangle must equal 180 degrees. If we know two of the angles, we must add them together, then subtract them from 180. 45 + 60 = 105, 180 - 105 = 75. The measure of the third angle is 75 degrees.
