Question 1192900
<br>
Let x be the measure of one of the angles.<br>
Then if "12 of the other" is interpreted as 12 times the other, the measure of the other angle is 12x+84.<br>
The sum of the measures is 180:<br>
(x)+(12x+84)=180<br>
Solve for x using basic algebra; then the two angles are x and 12x+84.<br>
