Ab is tangent to circle o at a. the diagram is not drawn to scale. if ao =30 and bc = 48 what is ab? a) 84
b) 78
c) 76
d) 72

91.19

Step-by-step explanation:

From the given diagram;

BO = 2 BC

BO = 2(48)

BO = 96

To get AB, we will use the pythagoras theroem;

BO² = AB² + AO²

96² = AB² + 30²

9216 = AB² + 900

AB² = 9216 - 900

AB² = 8,316

AB = √8,316

AB = 91.19

Hence the length of AB is 91.19

relating to or denoting a system of numbers and arithmetic based on the number ten, tenth parts, and powers of ten.

it alot will look like this 4.4

one set of data has more variation than the other. hope this !
