Answer:

$\frac{31}{20}\pi$

Step-by-step explanation:

The circumference of circle G is 2pi, which means that HJ is equal to 81/360*2pi = 9pi/20, which means that RJ is equal to 18pi/20-9pi/20 = 9pi/20. Therefore, RHJ is equal to the circumference of the area minus RJ, which is equal to 40pi/20 - 9pi/20 = 31pi/20

I hope this helps

Can you help me solve this proof please?

blagie [28]

So.. Wouldn't the angles be 90 degrees since they are perpendicular to each other?ABD and CBD are probably connected to each other by line BD so AC must form a straight line. AC is now perpendicular to BD, but I'm not sure how to prove AD and DC are congruent lines, unless lines are drawn to connect those points..
