Propagation of error 18. calculate the uncertainty in the answers of the following: (a) (128 + 2) + (10258) - (636. 4). (b) (16.25 +0.06) - (9.43 0.03), (c) (46.1 +0.4) + (9351). 19. calculate the absolute uncertainty in the answers of the following: (a) (2.78 0.04) (0.00506 + 0.6). (b) (36.2 +0.4)/(27.1 +0.6), (c) (50.23 0.07) (27.86 0.05)/(0.1167 +0.0003). 20. calculate the absolute uncertainty in the answer of the following: [(25.00.1) (0.02137 0.0003) - (1.02 +0.01)(0.112 +0.001)(17.0 +0.2)/(5.87 +0.01).

step-by-step explanation:

rectangles are made up of 4 right angles, which means that a side and a base meet perpendicular to one another.   their slopes then have to reflect perpendicular slopes.   perpendicular slopes are opposite reciprocals of one another.   for example, if the slope of one line is +2/3, then the perpendicular slope to that would be -3/2.   so we look for that combination in our choices.

all of them satisfy that condition (so what's the question, i guess? )
