Question

The three angles of a quadrilateral ae in the ratio 3:5:7:9. Find the measure of the fourth angle. please help​

Answer 1

The answer is 45,75,105,135

Sum of the angles of quadrilateral is equal to 360

⇒3x+5x+7x+9x=360

⇒24x=360

⇒x= 360/24

⇒x=15

Hence,

the angles of a quadrilateral are

3x=3×15=45

5x=5×15=75

7x=7×15=105

9x=9×15=135

Hence, 45,75,105,135 answer
