Question

PLEASE GIVE ME ANSWER PLEASE ​

Answer 1

sqrt((x2-x1)^2+(y2-y1)^2)

Answer 2

a)sol...A/Q

x+130=180(Sum of angles on a straight line is 180 degree)

=>x=180-130

=>x=50

Hrnce,the value of x is 50 degree.

b)sol...A/Q

`circumference\ of\ circle=2\pi y\\</p><p>2\pi r=2\pi y\\</p><p>r= (2\pi y )/(2\pi) \\</p><p>Hence,r=radius=y`
