Answer:

Arc AB is a semicircle, Not true.

Step-by-step explanation:

In circle O, central angle AOB has measure of 90°

We need to choose statement which is not true. We can see the attachment to shape of circle.  

As we can see O is the center of circle. A and B are two points on circle.  

So, OA and OB must be radius of this circle.  

1) Segment OA is a radius ( TRUE )

2) Segment OA and OB are perpendicular (TRUE)

Because central angle makes 90°  

3) arc AB is a semicircle (FALSE)

Because AOB is not 180°

Answer:

53.13

Step-by-step explanation:

To find the measure of an angle use an inverse trig function.

Sin A = \frac{4}{5} so you can take the inverse to find A sin^{-1}\frac{4}{5} = A.

Use a calculator to calculate the value.

A = 53.13
