Can someone please explain?
1 answer:
This is an isosceles triangle. The angles at the base are congruent (they have the same measures).
Look at the picture.
We know: The sum of the measures of angles in a triangle is equal 180°.
Therefore we have the equation:
<em>combine like terms</em>
<em>subtract 5 from both sides</em>
<em>divide both sides by 7</em>
