Question

i) Measures of angles of quadrifateral PQRS are in the ratio of 8:7:5:4 show that quadrilateral PQRS is a

trapezium​

Answer 1

let the angles be 8x , 7x , 5x , 4x

total 24x = 360

X = 15

angles are :- 8(15)= 120

7(15)= 105

5(15)= 75

4(15)= 60

since the angles are unequal.. hence apQRS is a trapezium..

hope it helps..

mark my answer as the brainiest
