(64)

The 6 in 36.4

Step-by-step explanation:

Well you have the ones and tens place

the 7 in 127.53 is in the ones place and

the 6 in 36.4 is in the ones place also

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

d

because parallelagram have all 4 angels the same size dependeing and a rectangle and square are oth parallelogram
