(5x+5) + (5x-5) = 90 degrees (since it’s a right angle)
take out of brackets: 5x+5+5x-5=90
put like terms together: 5x+5x+5-5=90
combine like terms: 10x=90
make x stand alone and divide 90 by 10: x=9
now that we know what x is, we can find the measures:
First one:
=5x+5
=5(9)+5
=45+5
=50
Second
=5x-5
=5(9)-5
=45-5
=40
Hope that helps!!!
