Question

in parellelogram pqrs angle p:s=4:5 find measure of all angle of paraellelo gram pqrs​

Answer 1

Answer:

p= 80; s= 100

q= 100; r= 80

Step-by-step explanation:

in a parallelogram sum of two adjacent angles ( angles on same side) is equal to 180 degrees

as p and s are on same side p+s=180

and given p:s = 4:5

let p= 4a ; s = 5a

then 4a + 5a = 180

this gives a = 180/9 = 20

then p = 4 × 20 = 80

q =5 ×20 = 100

as in parallelogram opposite angles are equal,

p= r = 80

q = s = 100
