Question

Find the value of z.

Answer 1

look up inscribed angles

Answer 2

If piR = 3/14 * 65, then 90L must be 90 * 64?

Answer 3

we know that angle abc is 85 degrees

we know that arc length is DC is 90 degrees and arc length CB is 64 degrees


now using the property of inscribed angles

we can conclude that angle AOC is equal to 2*85 degrees

or 170 degrees

this means that the arc length A"D"C

must be 170 degrees




NOW
remember that the total arc length of a circle is 360 degrees

since we know the arc length of ADC, and CB

we need to subtract those 2 from 360 degrees to get the arc length angle of AB

Answer 4

360 - 170 and 360 - 64?

Answer 5

360 - 170 - 64 = ? .........

Answer 6

126°
