Answer:
140°
Explanation:
Sum of interior angles for a quadrilateral = 360°
3 : 6 : 7 : 2 = 3+6+7+2 = 18
So the total of the ratios is 18 and to total of the angles is 360, use proportion to find the answer.
(I'll add x into this for solving purposes.)
18 x = 360
x = 20
Largest angle = 7x = 7 × 20 = 140°
