<PRE><B>Question 538947</B>
Call the smaller acute angle x and the larger y&lt;P&gt;
y=4x&lt;P&gt;
The sum of the interior angles in a triangle is 180 so&lt;P&gt;
x+y+90=180 and thus x+y=90.&lt;P&gt;
Solve by substitution.&lt;P&gt;
y=4x so&lt;P&gt;
x+4x=90
5x=90
x=18&lt;P&gt;
y=4x=4(18)=72
