I NEED TO GET 5 Right.SO SOMEONE HELP

Hey! So to find angle b you’ll first subtract 95 by 180 which will find angle ADC.

180-95=85

Now we know that sum of all angles = 180. Hence—>

34+85+x=180

=85+x=180-34
=85+x=151
=x=151-85
X=66

Now to check our answer—> 66+34+85=180, Therefore we are right…

Angle b=66 degrees

Hope this makes sense :)

Y= -2x-1 the negative in front of the 2 is because the slope is negative and the -1 is because it’s down 1 on the y axis.
