If one angle of triangle is 15° more than its second angle. The third – InterviewSolution

1.

If one angle of triangle is 15° more than its second angle. The third angle is 25more than double the second angle. Find the three angles of the triangle.

Answer»

st angle =x2 nd angle =2x-153 rd angle =2x-15+20

so,x + 2x-15+2x-15+20=1805x-10=1805x=190x=382x-15=612x-15+20=81
