For this problem you need to determine the correct height of a flagpole large enough to support the star spangled banner flag that flies over fort mchenry. this flag is 30 by 42 feet in size. (we know that the ratio of the height of a flagpole to the width of any flag is 1 to 4.)

jk it's 20

step-by-step explanation:

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92

m=-16
