In a right triangle.....one angle is 90o      the other two add to 90o

   in ratio of 3 to 7     one is   3 /(3+7) = 3/10ths   of 90      3/10 x 90 = 27o

                          and the other is   7/(3+7) = 7/10ths   of 90 =               63o

 

 

2 the angles add to 90

     x = one     the other is    2x -30

x    +    2x-30   = 90

 x =40          one angle is 40o    the other   is    2x-30   =   50o

I got the same for 1

1) the angles in this ratio 3:7 add up to 90. So 90/(10)=9, 9*3=27, 9*7=63. 63 is your answer, and checking, we have 63+27=90
