In the problem, the first equation should be represented like this base on the variable given in the problem:
20p + 9t = 44.4
with that equation, the second equation would is given by this formula, in response with the additional number of paperback and textbook
21p + 14t = 51
to get the system equation in getting the mass of each variable, you should subtract the two equation to simplified the formula.
20p + 9t = 44.4
- 21p + 14t = 51
-------------------------
p + 5t = 6.6 // this is the system equation that could be use in getting the mass of each object

Answer:
∠1 = 58°
∠2 = 122°
∠3 = 122°
Step-by-step explanation:
∠1 = 58°
∠2 = ∠3
∠2 = (360 - 58 - 58)/2 = 122°
∠3 = 122°
