IN circle O. PA and PB are tangents (the figure is not drawn to scale )Consider what you know about circles. How can this help you use one of the triangle congruence theorems?
What do you know

about the relationship of angles in congruent triangles and circles?
Think about how you can use angle AOP to calculate angle BOD.

Weegy can not answer this without the figure. However, you can check out this site for possible answers about your inquiry:

plz help on this question A forest ranger spots a fire from a 28-foot tower. The angle of depression from the tower to the fire is 11 . To the nearest foot, how far is the fire from the base of the tower? Show the steps you use to find the solution. **Weegy:** A forest ranger spots a fire from a 21-foot tower. [ The angle of depression from the tower to the fire is 12 degrees.
- - - - - - - - -
Draw the picture.
The angle of depression looking from the tower is the same as the angle
of elevation looking at the top of the tower from the spot of the fire.
- - - - -
So, tan(12 degrees)= 21/distance between tower and fire
distance = 21/tan(12) = 98.8 ft

jamie made a cylindrical vase in which the sum of the lateral area and area of one base was about 3000 square centimeters. the vase had a height of 50 centimeters. find the radius of the vase explain the method you would use to the find the radius **Weegy:** a cylinder's surface area (with one base) is defined as:
SA = pi(r^2) + 2(pi)(r)(h)
Since we know that the surface area was about 3000 square centimeters and that the height was 50 centimeters, [ we can use this information to find the radius:
3000 = pi(r^2) + 2(pi)(50)(r)
3000 = pi(r^2) + 100(pi)(r)
now use quadratic formula to solve for r:
0 = pi(r^2) + 100(pi)(r) - 3000
using quadratic formula, r is:
r = 8.78 cm

In circle O, PA and PB are tangents. (The figure is not drawn to scale.) a.Prove that APO = BPO b.Find m BOD for m AOP = 64. Explain your reasoning. **Weegy:** the general rundown would be:
tangents are 90 degrees to the radius; line PO is common to both triangles
since the raduis create the same side lengths for each triangle; then we has an SSA congruency [ ] (More)
