The hundreds digit and the ones digit of a three digit number are the same. The sum of its tree digits are 16. If the tens digit
tensa zangetsu [6.8K]
<h2>727</h2>

Step-by-step explanation:

       Let us denote the three digit number by abc, where a is the hundreds digit, b is the tens digit and c is the ones digit.

       Hundreds digit = a = Ones digit = c

       Sum of digits = a+b+c=16

       So, 2c+b=16

       On exchanging tens and ones digit, value increases by 45. So acb is 45 greater than abc.

       acb-abc=45

       100a+10c+b-100a-10b-c=45\\9c-9b=45\\c-b=5

       2c+b=16,c-b=5\\3c=21\\c=7=a\\b=2

∴ Required number is 727

Emily thought of a counting number, and then she added the next counting number to it. She got the sum of 57. What was Emily’s n
Dovator [93]
Let this number be x. The next number is (x+1). And their sum is 57. Then, we have to solve this equation x+x+1=57
                                       2x=56
                                       x=28
Emily's number was 28

The complement of an angle is one-sixth the measure of the supplement of the angle. What is the measure of the complement angle?
cestrela7 [59]

Answer:

The measure of the complement angle is 18\°

Step-by-step explanation:

Let

x-----> the angle

we know that

The complement of an angle is equal to (90-x)\°

The supplement of an angle is equal to (180-x)\°

we have

The complement of an angle is one-sixth the measure of the supplement of the angle

(90-x)\°=(1/6)(180-x)\°

solve for x

(540-6x)\°=(180-x)\°

(6x-x)=(540-180)\°

(5x)=(360)\°

x=72\°

Find the measure of the complement angle

(90-x)\° ------> (90-72)=18\°
