Answer:
x = 3 ft
y = 83
Step-by-step explanation:
DEFG ≅ SPQR
So, corresponding part will be congruent
∠D ≅ ∠S ; ∠E ≅ ∠P ; ∠F≅ ∠Q ; ∠G ≅ ∠R
DE = SP
x = 3 ft
Sum of interior angles = 360
∠D + ∠E + ∠F + ∠G = 360
∠S + (y+3) + ∠Q + (y +1) = 360
107 + y + 3 + 83 + y+1 = 360
194 + 2y = 360
2y = 360 - 194
2y = 166
y = 166/2
y = 83
