Question 176927
we know that the two angles equal 90 degrees so one angle we will call x and the other we will call y and that is equal to 90-x
:
so lets write this as a proportion
:
so {{{1/4=x/(90-x)}}}
:
{{{4x=90-x}}}cross multiplied
:
5x=90
:
{{{highlight(x=18)}}}degrees is one angle
:
{{{highlight(y=90-x=90-18=72)}}}degrees is the other angle
:
18/72=1/4
