Answer 1

Answer:

Hey mate ,

your answer is

$\sqrt{3}$

Explanation:

From the figure , the angle of arc AOB is

$theta \: = 180 - 60 \\ theta \: = 120 \\ \\ in \: triange \: aob \\ oa = ob = r \\ \\ therefore \: \: triangle \: abo \: is \: isosceles \: angle \: triangle$

Length of the base of isoceles angled triangle is calculated by -

$s \: = \: 2r \: \sin(theta) \div 2 \\ \\ s = 2r \: \sin(120) \div 2 \\ \\ s = 2r \: \sin(60) \\ \\ s \: = \: 2r \: \times \sqrt{3} \\ \\ s = \sqrt{3} r$

Hope this will help uh !
