Question 185089
<font face="candara">
Note: Let A and B be angles with measures x and y, respectively. If x+y=180, then the two angles are supplementary.
::
Let x=measure of one angle
Then 3x+10 [ten degrees more than three times the other]=measure of the other angle
::
IF the angles are supplementary, then:
:: x+(3x+10)=180
:: 4x+10=180
:: 4x=170
:: x=170/4=42.5<sup>o</sup>. The other angle is 180-42.5=137.5<sup>o</sup>
