Find the value of x
angles of a polygon​

148°

Step-by-step explanation:

In circle geometry, angle at the center is twice angle at the circumference

Angle at the center = x°

Angle at the circumference= 74°

Hence x = 2(74)

x = 148°

Hence the value of x is 148degrees

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or
