Answer 1

Answer:

x= 45° y=100°

Step-by-step explanation:

In parallelogram opposite angles are equal. So

angle A= angle C

(3x-10°) = (x+80°)

3x-x=80°+10°

2x=90°

x=90°/2

x=45°

And also in parallelogram sum of adjacent angles is 180°

angle A+ angle D= 180°

3x-10° + y+25° = 180°

putting value of x; 3*45=135°

135°-10°=y+25°

125°=y+25°

y= 125°-25°

y=100°
