Answer:
151 degrees
Step-by-step explanation:
This triangle has supplementary angles, so we need the triangle to add up to 180 degrees.
Start off with 61 degrees, below the 61 degrees symbol, there is a right angle under it, a right angle equals to 90 degrees. Then subtract 90 from 61, so the last angle is 29 degrees.
Then subtract 180 from 29, then your answer is 151 degrees.
Answer/Step-by-step explanation:
<u><em>George: </em></u>
4.3% ÷ 100 = 0.043
0.043 × 5000 = 215
<em><u>John:</u></em>
4% ÷ 100 = 0.04
0.04 × 5500 = 220
<u><em>End of 6 years:</em></u>
George: 215 × 6 = 1290
John: 220 × 6 = 1320
<u><em>John has earned the most interest at the end of 6yrs.</em></u><u><em> $1320</em></u>

-25 is an integer and a rational number.
<h3>What is number system?</h3>
- A system of writing numbers is known as a number system.
- It is the mathematical notation for consistently employing digits or other symbols to represent the numbers in a particular set.
- It represents the arithmetic and algebraic structure of the numbers and gives each number a distinct representation.
Now,
- Natural numbers are positive integers with a range of 1 to infinity; nevertheless, they do not include zero. -25 wouldn't be a natural number because it is a negative number.
- A group of numbers known as a whole number consists of all positive integers and 0. This wouldn't be a whole number because -25 isn't a positive number.
- Any real number that cannot be represented as the quotient of two integers is said to be irrational. Square roots of irrational numbers are also frequently seen. -25, however, is not a square root.
- Any number that can be expressed as a ratio, or a fraction, of two integers, is referred to be a rational number. Fractions, decimals, negative decimals, and other rational numbers are very prevalent. Since -25 can be represented as a ratio of two numbers. it is a rational number.
- A whole number that can be either positive, negative, or zero is known as an integer. As -25 is negative and a whole number( when positive), it is an integer.
Hence, -25 is an integer and a rational number.
