Question

If an angle of parallelogram is two third of adjacent angle, then the angles of the parallelogram are

a) 108°, 72°, 108°, 72

b) 110°, 70°, 110, 70°

c) 96*, 84", 96", 84*

d) All of the above​

Answer 1

Answer:

a) 108° , 72°

Step-by-step explanation:

let the one of the adjacent angle be x°

other angle = 2x/3 °

as we know sum of adjacent angles of a llgm is 180°

so,

(x+2x/3)° = 180°

5x/3= 180°

x = 180*3/5

x= 108°

1st angle = 108°

2nd angle = 108°*2/3= 72°

similarly the other 2 angles will be 108° and 72°
