20 points pl ∠4=? a. 120 degrees b. 50 degrees c. 30 degrees d. 150 degrees ∠6= a. 150 degrees b. 130 degrees c. 15 degrees d. 30 degrees ∠8= a. 30 degrees b. 132 degrees c. 20 degrees d. 150 degrees ∠7= a. 130 degrees b. 30 degrees c. 150 degrees d. 15 degrees the last question is in the file the answers for the last question is a. a and c b. b and c c. a and b d. none of the above

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
