Question

If angles P,Q,R and S of a quadrilateral are in the ratio 3:4:6:7 ,then calculate the measure of each angle. Is PQ || RS ? Justify your answer.

Answer 1

no pq not parllel to rs

Answer 2

Answer:

54°,72°,108°and 126°,yes PQ ll SR

Step-by-step explanation:

GIVEN: PQRS in the ratio 3:4:6:7

solution:

PQRS= 3x+4x+6x+7x= 360°

20x=360°

x=360/20

x= 18

hence the angles are

3x= 3×18=54°

4x= 4×18=72°

6x= 6×18=108°

7x= 7×18=126°

check:

54°+72°+108°=126°=360°

answer.
