Question

Find the measure of the indicated arc

Answer 1

Explanation:

We know that if an arc subtends an angle of theta , with a radius r , then the measure of arc is r× theta . Here theta is 109° .

`\implies l = r\theta \\\\\implies l = r* 109^(\circ)\\\\\implies l = r * (109)/(180)\pi rad \\\\\implies \boxed{\boxed{ l = 0.6\pi r m }}`

where r will be the radius .
