The angles of a quadtilateral are x°,(x+10°) ,(x+30°)and 2x° .find the angle |
|
Answer» Step-by-step explanation: ❥︎The sum of quadrilateral is 360°.5x + 20= 360 5x = 360-20 5x = 340 x = 340/5 x = 68 First ANGLE = 68°. Second angle = x-10 = 68-10 = 58°. Third angle = x+ 30 = 68+30 = 98°. Fourth angle = 2x = 2× 68 = 136°. The smallest angle is = 58°, second angle. |
