Answer 1

Answers: (c) 30°

x+30+3x+x=180°

5x+30=180°

5x=150°

X=30°.

Answer 2

Sum of angles of a circle is 360°

and opposite angles are equal.

Therefore,

$3x + 3x + x + x + x + 30 + x + 30 = 360$

$6x + 2x + 2x + 60 = 360$

$10x = 360 - 60$

$10x = 300$

$x = 30$

The value of 'x' is

(C) 30°
