Suppose that qrs is isosceles with base sq . suppose also that =m∠r+3x47° and =m∠s+4x6° . find the degree measure of each angle in the triangle.

ANSWER




and



EXPLANATION

Since the triangle is an isosceles triangle, the base angles are equal.

The three interiors angles of the triangle are,



The sum of these three angles must equal 180°.



We group like terms to get,



This simplifies to,



We divide both sides by 11 to get,



The measure of the angles are,

Y=-2x-6 is the answer
