Question 964023
The hole diameter on top of the sheet is 0.220.
The angle is 100.
The thickness is 0.048.
Let's call the hole diameter on bottom of the sheet {{{D}}}.
{{{drawing(300,300,-10,10,-10,10,blue(line(-8,5,8,5)),blue(line(-5,-5,5,-5)),locate(-1,6.5,D),locate(6,6.5,x),locate(-5.75,-1,A),locate(-6.5,6.5,X),locate(-4,1,0.048),green(line(-5,-5,-5,5)),green(line(5,5,5,-5)),line(-5,-5,-8,5),line(5,-5,8,5)))}}}
From the diagram,
{{{A=50}}}
.
.
{{{D+x+x=0.220}}}
{{{D+2x=0.220}}}
.
.
{{{tan(A)=x/0.048}}}
{{{x=0.048tan(50)}}}
{{{x=0.0572}}}
So then,
{{{D+2(0.0572)=0.220}}}
{{{D=0.220-0.1144}}}
{{{D=0.106}}}
