Marcus ran 43.74 miles.
Take 90% of 48.6 miles by multiplying .90 by 48.6
48.6(.90)=43.74 miles
This is the isosceles triangle. Therefore, the angles at the base are congruent.
We know that the sum of the measures of the angles in a triangle is 180°.
Therefore we have the equation:
<em>subtract 38 from both sides</em>
<em>divide both sides by 2</em>
