Find the unknown for every letter

Answer 1

x = 70°, y = 110°, z = 70°

Explanation:

The two straight lines are intersection each other.

y = 110° [justification vertical angles, or vertically opposite angles]

x + 110° = 180 [supplementary angles]

therefore x = 180-110 = 70°

Similarly,

z + 110° = 180 [supplementary angles]

therefore z = 180-110 = 70°

Answer 2

Y= 110°

Z= 70°

X= Z, which is 70°

Explanation:

Because 110° is same to y, y=110°.

A 180° angle is a straight line, so 180-110=70.

Thus, z is 70°

Because x is same to z, it is 70° too.
