Question

find the unknown sizes of angles. please tell me properly by doing copy and notebook step by step​

Answer 1

Answer:

Given

X+120 = 180 ( adjacent angles are equal to 180)

X=180-120

X=60

X=Y ( opposite angles are equal)

Y = 60

Z+60= 180( adjacent angles are equal to 180)

so, Z= 180-60

Z =120
