Question

Three angles of a quadrilateral are in the ratio 4:6:3. If the fourth angle is 100° , find the other

three angles of quadrilateral.​

Answer 1

Answer:

If the fourth angle is 100 degrees the angle remains will be equal to 360 - 100 = 260 degrees, THE OTHER THREE ANGLES ARE AT THE RATIO 4 : 6 : 3, Which means its value will be 4x , 6x , 3x.

Answer 2

Step-by-step explanation:

angle A + angle B + angle C + angle D = 360°

100° + angle B + angle C + angle D = 360°

angle B + angle C + angle D = 360° - 100°

angle B + angle C + angle D = 260°

4 + 6 + 3 = 260°

13 = 260°

(1) 13...................260°

4.................... ?

260×4/13= 80°

(2) 13...................260°

6 .................... ?

260×6/13= 120°

(3)13...................260°

3.................... ?

260×3/13= 60°
