Answer:
C. 320
Step-by-step explanation:
Given:
As we can see in the photo, PR and QR are perpendicular with each other at the angle PAQ => the angle QAR = 90°
=> arc PR = 360°/2 = 180°
=> mTAU = 180° - mRAS -mSAT - mPAU = 180° - 50° + 40° + 40° = 50°
Hence, mPRU = mRAS + mSAT + mTAU + arc PQ
= 50° + 40° + 50° + 180°
= 320°

Step-by-step explanation:
One way to approximate the derivative at a point is by finding the slope of the secant line between points on either side. That is what is done in the attached spreadsheet.
f'(0.1) ≈ (f(0.2) -f(0.0))/(0.2 -0.0) = -5 . . . for example

Another way to approximate the derivative is to write a polynomial function that goes through the points (all, or some subset around the point of interest), and use the derivative of that polynomial function.
These points are reasonably approximated by a cubic polynomial. The derivative of that polynomial at the points of interest is given in the table in the second attachment. (f1 is a rounding of the derivative function f')
