Answer 1

Answer:

In the first case , y° = 105 °

In the first case , x° = 150° , and the fourth angle is also 150°.

Step-by-step explanation:

Y° = 105° because the opposite angles are equal.

X° = 150° because angle1 + angle2 + angle3 + angle4 = 360°

= 105° + 105° + X° + angle4 = 360°

= 210° + X° + angle4 = 360°

= X° + angle4 = 360° - 210°

Therefore, X° = 150°.

Angle4 is also equal to 150° because opposite angles are equal [ X° is opposite to angle4.]

THEREFORE,Y° = 105° & X° = 150°.
