Question

Can I know the answer for xi one with reasons
Pls answer fast I have exam tomorrow

Answer 1

Answer:x=70 y=290

Step-by-step explanation:

Acc. To me

Both lines go parallel so if you draw perpendicular line on it .it make 90

If you draw perpendicular line at last point of parallel line so

Total angle is 160 ,you draw perpendicular line that make angle90 so minus it

160-90=70

On second line do same you found

130-90=40

Then you see 70,40,x make triangle

We know that triangle have total 180

So 70+40+x=180

Then x=70

You see x+y=360

Becz total rotation is 360

So y=290.

I hope i help.
