The measure of the central angle aob is by 30° greater than the measure of the inscribed angle which intercepts arc ab. what are the measures of these angles?

Step-by-step explanation:

The central angle is double the inscribed angle for the same intercepted arc. Since doubling the angle adds 30° to it, the original inscribed angle must be 30°.

Then the central angle is 30°+30° = 2·30° = 60°.

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
