Two numbers have a sum of 32. One number is 6 more than the other. Find the numbers
Vlad [161]
<h2>Answer: 13 & 19</h2>

<h3>Step-by-step explanation:</h3>

Let the bigger number be 'U' and the smaller number 't'.

Since the two numbers have a sum of 32, then   U + t = 32.

& since one number is 6 more than the other, the U - 6 = t

⇒ U + U - 6 = 32

             2U = 38

                U = 19

By substituting fot the value of U we found,

19 - 6 = t

      t  = 13

<h3>∴ the numbers are 13 & 19.</h3>

the measure of an angle is fifty nine times the measure of its supplementary angle. What is the measure of each angle
Dimas [21]

9514 1404 393

Answer:

  177°, 3°

Step-by-step explanation:

If the smaller angle is s, then the sum of the two angles is ...

  s + 59s = 180°

  s = 180°/60 = 3° . . . . . divide by the coefficient of s

  59s = 177° . . . . . . . . . find the larger angle

The two angles are 177° and 3°.
