Question

In a quadrilateral PQRS, if angle P=60°and angle Q: angle R: angle S=2:3:7,then angle 5=​

Answer 1

Step-by-step explanation:

Let the ABCD is a quadrilateral witch ∠A,∠B,∠Cand∠D in ratio 3:7:6:4

Sum of ratio 3+7+6+4=20

∠A+∠B+∠C+∠D=360

0

∴∠A=

20

3

×360=54

0

∴∠B=

20

7

×360=126

0

∴∠c=

20

6

×360=108

0

∴∠D=

20

4

×360=72

0

Then ABCD is a quadrilateral is trapezium
