Question

the angles of a quadtilateral are x°,(x+10°) ,(x+30°)and 2x° .find the angle​

Answer 1

Step-by-step explanation:

❥︎The sum of quadrilateral is 360°.

So, x+ x-10+ x+30+2x=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.
