Step-by-step explanation:

B = 42°

Complement of B = 90°-B = 48°

3x-8 = 2x+1

x = 9°

A = 71°

Supplement of A = 180°-A = 109°

x + (5x) = 180°

x = 30°

A straight angle is 180°

78 = 5x-2

x= 16°

C = 110°

Supplement of C = 180°-C = 70°

119 + m = 180

m = 61°

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

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

you,
