25° 35° to 205° circle ​
Lisa [10]

Answer:

x = 60

Step-by-step explanation:

the chord- chord angle x is half the sum of the measures of the arcs intercepted by the angle and its vertical angle.

The sum of the arcs in a circle = 360° , then

intercepted arc = 360° - (35 + 25 + 205)° = 360° - 265° = 95°

then

x = \frac{1}{2} (95 + 25 ) = \frac{1}{2} × 120 = 60
