Answer:
110° and 29°
Step-by-step explanation:
(a)
x and 110° are alternate exterior angles abd are congruent, then
x = 110°
(b)
∠ ECD = ∠ FBC = 61° ( corresponding angles )
the sum of the 3 angles in Δ CDE = 180° , that is
x + 61° + 90° = 180°
x + 151° = 180° ( subtract 151° from both sides )
x = 29°
