Your Turn: Use the same triangle as above to find the trigonometric functions for the triangle
Sc(B) =
sec(B) =
cot(B) =

it is x=-4

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

i'm assuming that it's c.)   volcanoes built the mountains and earthquakes tore them down.

$450 i think. hope this ☺
