Answer:
(d). 
Step-by-step explanation:
sin² β + cos² β = 1
cos (α + β) = cos α cos β - sin α sin β
cos α = √(1 - 
) = 21 / 29
cos β = 12 / 13
sin β = √(1 - 
) = 5 / 13
sin α = 20 / 29
cos (α + β) =

The problem wants to calculate the percentage error of the measurement of 7cm and if the measurement is uncertain we could use the formula of getting the error by margin of error over measurement time 100% and base on the data, the error would be if the margin error is 7.5 is 107 %. I hope you are satisfied with my answer
