M< AED = 16y + 10. Find the value of y so that ED I AB.

Full question attached:

Answer and explanation:

To calculate y in the equation <AED=16y+10 we first find the value of angle AED from the diagram(attached)

From the diagram, we can see that <AED = 180 degrees given that <AED is angle on a straight line=180 degrees.

The line AB is therefore perpendicular to line ED

Hence we calculate y in the equation <AED= 16y+10

180= 16y+10

180-10=16y

16y=170

y=170/16

y= 10.625

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°
