Can you help me with these questions? Picture shows the questions but, I'll type them as well.
1a : find the length of AK and BK
1b : if AC= 7, then how long is BC?
2a : find the measure of angle AKB?
2b : what about angle ADB?
2c : what's the measure of angle ACB?
3a : find the arc length of arc AB?
3b : Find the area of sector AB?

Best ResponseYou've already chosen the best response.2useful information CK is the bisector cbk = cak arc AB = angle AKB given circle = 360 degrees Cbk = cak = 90 degrees tangent with radius arc length is proportional angle formed angle/360 = length/circumference circumference = 2*pi*radius area of sector to area of circle in same ratio as angle of sector area of sector = angle/360 * area of circle (pi*r^2)
