Question

can someone show me how to do this if m angle dab=2x-9 and m angle bdc=7x-27 solve for m angle dab

Answer 1

can someone please help explain how to do this

Answer 2

suppose abcd wann being a rectangle ,yes

so then you know that a rectangle has angles equal 90 degree

so this mean that 2x-9=90 and 7x-27=90

2x-9=90
2x=99
x=99/2

7x-27=90
7x=117
x=117/2

or you can writing

dab = bdc

2x-9=7x-27

-9+27=7x-2x
18=5x

x=18/5

so do you can rewrite the exactle text of exercise please because i think you have missed anything
