Answer:
Step-by-step explanation:
You have to assume that P is the center of the circle. Without that fact, there is no answer.
Both PT and PB are radii. Therefore the triangle containing <PTB and <PBT is isosceles. What that means is that angle PTB = angle PBT
So angle PBT is the answer.
Y=19, It's a straight horizontal line.
Answer:
D = 90°
E = 147°
F = 33°
Step-by-step explanation:
E:
E is 147°, because it is vertical to the angle 147°
F:
F is 33°, because 147* is its supplementary angle, or angles that add up to 180°
D:
D is worth 90°, because its supplement is worth 90°

Is there an answer to this equation such as 2x-3+8=4?
Answer:
8%
Step-by-step explanation:
Given that:
Reliability of each = 0.92
r = 0.92
1 - (1 - r)(1 - r) = 1 - (0.08)(0.08) = 1 - 0.0064 = 0.9936
Percentage improvement :
1 - (0.9936) / r
1 - (0.9936 / 0.92)
1 - 1.08
= - 0.08
= 0.08 / 100 = 8%
