AOD = 180 - (90+32) = 58 because when a tangent meets a radius they form a right angle
ABC = 1/2 AOD = 29 because it's subtended by the same ark as the AOD and O is center of the circle
Answer:
$180
Step-by-step explanation:
Since the cost of the telescope with the 30% discount is $126 then $126 is 70% of the original price. Remember 100-30=70. To find the original price set up a proportion with these values:

Solve for the original price by cross multiplying numerator with denominator.
x(70) = 126(100)
70x = 12600
x= $180
5.575 because you would need to add half of 0.05 which is 0.075
I think this right : )
