Answer: 140 degree Step-by-step explanation: The angles of a quadrilateral are given as in the ratio 2:3:6:7 Let the angles be 2x, 3x, 6x, 7x. The sum of angles of a quadrilateral = 360° ⇒2x+3x+6x+7x = 360 ⇒18x = 360 ⇒x = 360/18 ∴x = 20 ∴The largest angle = 7x = 7×20 =140° Reply
Answer:
140 degree
Step-by-step explanation:
The angles of a quadrilateral are given as in the ratio 2:3:6:7
Let the angles be 2x, 3x, 6x, 7x.
The sum of angles of a quadrilateral = 360°
⇒2x+3x+6x+7x = 360
⇒18x = 360
⇒x = 360/18
∴x = 20
∴The largest angle = 7x = 7×20 =140°
Answer:
the largest angle is 140 degree
