Line AC is perpendicular to the
IRINA_888 [86]

If the length of OA is 1.80 units. Then the length of segment AB will be 0.80 units.

<h3>What is a Pythagoras theorem?</h3>

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

More about the Pythagoras theorem link is given below.

How do you calculate interest?
xxMikexx [17]
Well let’s say you put $100 in the bank. And they charge 10% interest. And 10% of $100 is 10. So it would be $10 interest.

90 points!!! Algebra - Please check these
Korvikt [17]

First picture:

2 and 7 are alternate exterior angles, which when added together need to equal 180 degrees.

Angle 7 = 180 - 146 = 34

Answer is B.34

Second picture:

Angle 8 = 48

Angle 8  + angle 7 = 180

Angle 7 = 180 - 49 =  131

Angle 5 and angle 7 are vertical angle, so angle 5 = angle 7 = 131

Angle 6 is a vertical angle to angle 8 so = 49

Angle 1 = angle 5 = 131

Angle 2 = angle 6 = 49

Angle 3 = angle 7 = 131

Angle 4 = angle 8 = 49
