This means that angle ACD is also 45
ACD and ACB are supplementary which means they add to 180 as well

Drew wrote a four digit number less than 2000. The sum of its digit is 20. Only the digits in the ones place and hundreds place
jeka94
He wrote the number 1892, because:

The number needs to be less than 2000, with four digits. Because the first is half the last, it means that the number must be 1??2.

These two numbers add up to 3, and all together, they need to add to 20. 20-3=17. The remaining numbers need to add to 17.

The only two single digit numbers that can add to 17, are 8 and 9. Therefore, the number must either be 1892 or 1982.

The second digit needs to be even, meaning that the number has to be 1892.

I hope this helps.

Which simplified fraction is equal to 0.53? 1) 24/45 2) 8/15 3) 48/90 4) 5/9
Shalnov [3]

To express a decimal number (with a finite decimal expression) in a fraction, you work like this: the numerator is the number without decimale separator (you simply pretend it's not there), while the denominator will be 10^n, where n is the number of digits after the decimal separator.

So, in your case, the number without decimal separator is 53, and you have two digits after the decimal separator, so the fraction will be

0.53 = \cfrac{53}{10^2} = \cfrac{53}{100}

which is irreducible.
