Please help this is urgent!
Find the measures of the 4 angles.

1. <1 = 133  (this is because 180 - 47 = 133)

2. <8 = 133 (this is because <8 is alternate exterior to <1, so they are congruent and equal)

3. <4 = 133 (this is because 180 - 47 = 133)

4. <5 = 133 (this is because <2 is 133 degrees and we know that it is corresponding with <6, so they are equal. subtract 47 from 180 and you get 133 degrees)

they're all 133 degrees! i hope this helps!

Step-by-step explanation:

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3
