Question

Two adjacent angle of a parallelogram are in the ratio 2:3 . Find the measure of all angels

Answer 1

Step-by-step explanation:

we know that , sum of adjacent angle of a paralellogram is 180.

so,

let the angle be x,

then,

2x + 3x = 180

= 5x = 180

= x = 36

hence, the angle of adjacent be 36×2 = 72

and , 36×3 = 108

Answer 2

Answer:

parallelogram = 360°

and opposite sides are parallel

therefore a=c and b=d

let 2:3 be 2x , 3x

2x+2x+3x+3x =360°

10x = 360°→ x= 360/10

x= 36

2x= 72 and 3x= 108

therefore a and c = 72 and b and d = 108

verify:

72+72+108+108 = 360°
