the value of a, y & z.
By
A
C С​

Answer 1

Answer:

the answer is the following

Step-by-step explanation:

z=75°

y=70°

x=35°

Answer 2

$\sf ∠D = ∠A \: (Alternate \: interior \: angles) \\ \\ ⇒ z = 75°$ $\sf ∠B = ∠C \: (Alternate \: interior \: angles) \\ \\ ⇒ x = 35°$ $\sf Sum \: of \: all \: the \: angles \: of \: a \: triangle = 180° \\ \\ ⇒ 35° + y + 75° = 180° \\ \\ ⇒ y = 70° \\ \\ Therefore, \\ \\ x = 35° \\ \\ y = 70° \\ \\ z = 75°$
