If the length of OA is 1.80 units. Then the length of segment AB will be 0.80 units.
What is a Pythagoras theorem?
The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.
The Pythagoras theorem formula is given as
H² = P² + B²
Line AC is perpendicular to the circle centered at O with a radius of 1 unit. The length of AC is 1.5 units.
The figure is shown below.
Then the length of segment AB will be
AB = OA - OB
AB = OA - 1
Then the OA will be
OA² = OC² + AC²
OA² = 1² + 1.5²
OA² = 1 + 2.25
OA² = 3.25
OA = 1.80 units
Then we have
AB = 1.80 - 1
AB = 0.80 units
