If a point is picked at random from the largest rectangle, what is the probability that it is not shaded? assume that all of the
smallest triangles are congruent.
a. 4/16
b. 7/16
c. 9/16
d. 15/16

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

h= 12 inches

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

its line 2 i just added the rest or else it wouldn't let me answer
