Answer:
The measure of angle ERK is 55°
Step-by-step explanation:
step 1
Find the measure of arc EK
we know that
The diameter divide the circle into two equal parts
In this problem
EOR is a diameter
see the attached figure to better understand the problem
so
arc EK + arc RK=180°
substitute the given values
arc EK + 70°=180°
arc EK=180°-70°=110°
step 2
Find the measure of angle ERK
we know that
The inscribed angle is half that of the arc it comprises.
m∠ERK=(1/2)[arc EK]
substitute
m∠ERK=(1/2)[110°]=55°
The answer is c) 45 times PI cubed.
