Help!

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?

6 on both sides and twelve on the top and the bottom
