Question

1)Each of the 2 equal angles of triangle is twice the third angle.Find the angle of the triangle.
2) Among 2 supplementary angles the measure of the larger angle is 36degree more than the measure of the smaller.find the measure

Answer 1

1.   third  angle  of the triangle  =  x (say)     First angle  of the triangle = 2x     second angle of the triangle = 2x sum of angles in  a triangle is 180 degrees
     1st angle + 2nd angle + 3rd angle = 180degrees      2x+2x+x =  180 degrees       5x = 180 degrees        x = 180 divide by 5       x = 36       1st angle = 2x = 36 multiply by 2       2nd angle = 2x = 36 multiply by 2       3rd angle = x = 36
