Same question was posted earlier .... I repeat my answer here ...
Question (2a):
Given that sum of triangle = 180°
∠1 + ∠2 + ∠3 = 180°
∠3 = 180° - ∠1 - ∠2 ---------------- (1)
Given that sum of angles on the adjacent line = 180°
∠3 + ∠4 = 180°
∠4 = 180° - ∠3 ------------------------(2)
Sub (1) into (2)
∠4 = 180° - (180° - ∠1 - ∠2 )
∠4 = 180° - 180° + ∠1 +∠2
∠4 = ∠1 +∠2 (proven)
Question (2b):
∠4 = 52° + 25°
∠4 = 77°
Both pairs of opposite sides of parallelogram are adjacent

Equation: 300+35x=1700; where x represents the amount of teams participating in the tournament
Answer: 40 teams competed in the lacrosse tournament
How to solve-
300+35x=1700
300-300+35x=1700-300
35x=1400
35/35x=1400/35
x=40
