Please help me find out the answer I am request you to find out the answer if you don't know the answer don't answer it and do all questions please ​

Answer 1

Answer:

x = 90

y = 30

z = 90

Step-by-step explanation:

triangle ABC is a 30 , 60 , 90 triangle because

60 + 30 + z = 180

90 + z = 180

bring 90 to other side

z = 180 - 90

= 90°

since DE is parallel to BC so

angle B = angle y

angle x = angle z
