bro written wrong in the question
one of the exterior angle =105degree
than we know that = interior angle +it's exterior angle =180degree
so if exterior angle is 105 degree than its interior angle will=180-105degree=75degree
we also know that sum of the all interior angle =180degree
it mean that
first angle +second angel +third angle=180degree
here first angle =75degree
than the sum of the second and third angle=180degree-75degree=105degree
here we able to know that exterior angle=sum of two interior opposite angle
ratio for second and third angle =2isto5
than 2+5=7
105/7or105divide by 7=15
second angle =15*2=30
third angle =15*5=75
one of the exterior angle =105degree
than we know that = interior angle +it's exterior angle =180degree
so if exterior angle is 105 degree than its interior angle will=180-105degree=75degree
