Question
The measures of two angles of a triangle are in the
ratio 3 : 7. If the sum of these two measures is equal to the measure of the third angle, then find the smallest angle.Solution
Let the angles of triangles =A, B and C A B C 3 : 7 : 10 The sum of triangle angles =180 ATQ- 20 =180° 1=9° Smallest angle =3×9° =27°
