Yea, sure thing...

So like, in a quadrilateral the sum of its angles will form 360°.

So,

(2x - 16)° + 2x° + x° + (x + 10)° = 360°

2x - 16 + 2x + x + x + 10 = 360

2x + 2x + x + x - 16 + 10 = 360

6x - 6 = 360

6x = 360 + 6

6x = 366

x = 366 ÷ 6

x = 61.

m<R = 2x° = 2 × 61 = 122°.

Hope it helps ya mate :))
