Find the coordinates of the fourth vertex that completes the construction of the rectangle on the coordinate plane. A) (2, −4) B) (4, −2) C) (−2, 4) D) (−4, 2)

x= 149. 24+7=31. 180-31=149

your welcome

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

answer: #1 ads up by 8 and i don't know #2

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
