a) Write an equation that can be used to determine the value of x.

b) Solve your equation from part a. Show all work.

c) What are the measures of ∠ 1∠ 2? Show all work.

a) x + 3 = 5 × 4

b) As with any sum, do the multiplication first. 5 × 4 = 20

So x + 3 = 20

The next step is to take three away from both sides

x + 3 - 3 = 20 - 3

20 - 3 = 17.

c) They are angles? is there the shape?

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
