a triangular playground has angles with measures in the ratio 5 : 6 : 4. What is the measure of the smallest angle

The smaller angle is 36˚ Explanation: The angles of the triangle can be rewritten as 3x,5x,7x We know the sum of the angles in every triangle is 180˚ Therefore 3x+5x+7x=180 15x=180 x=12 This means the smallest angle is 3(12)=36˚ Hopefully, this helps!
