What is the perimeter of the rectangle shown on the coordinate plane, to the nearest tenth of a unit?

15.3 units

20.4 units

30.6 units

52.0 units

The perimeter of the rectangle shown on the coordinate plane of points (-6,4), (-7,-1), (3,-3) and (4,2) is 30.6 units. The length of one side of the rectangle is 5.10 units and the other side is 10.20 units. To calculate the perimeter of a rectangle 2L+2W= 30.6 units.

answer: i think one of the answer is $150 and $300?

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
