The angle of NPR is 130°
First, set up an equation to find x.

Then, solve the equation for x.

Then, substitute 25 in for x in 2x
50
Finally, subtract 50 from 180 to find the angle of NPR
130°
Answer:
$850
Step-by-step explanation:
Multiply the $125 per lesson by 12 and that's $1500. Now add the $50 fee to make it a total of $1550. Subtract $1550 by $700 and you're left with $850 that you still need to pay.
Segment OX will be the radius.
YZ will be the tangent.
PQ might be the secant.
Hope this helps :)
