Question

three angles of a quadrilateral are in the ratio 3:
4:5 the difference of the least and the greatest of the angles is 45°​

Answer 1

Step-by-step explanation:

given :

three angles of a quadrilateral are in the ratio 3:

4:5 the difference of the least and the greatest of the angles is 45°

solution :

• 5x - 3 x = 45

• 2x = 45

• x = 22.5

• 3x= 3x22.5 = 67.5

• 4x=4x225= 90.0°

• 5x=5x22.5=112-5

• Pouxthangle = 360-(67.5+90+112.5) → 36⁰° - (180-0°+90)

• = 360°-270°

• = 90 degree
