Step-by-step explanation:
First find the angle BAC
BAC= 180 -(90+50) ( interior angle of triangle is 180)
BAC= 180- 140
= 40 degrees
sin 40= opposite/ hypotaneus
sin 40 = 2/ hyp
0.6427 = 2/ hyp
hypotaneus = 2/ 0.6427
hypotaneus = 3.1118
AB= 3.1118
to nearest hundredth = 3.11
The answer is: " 3 inches " .

No, because x/2 divides x by two, while -2x multiplies x by -2.
Answer:
15 1/6
Step-by-step explanation:
change -8 2/3 into an improper fraction = -26/3
-4/7v = -26/3
cross-multiply:
3(-4v) = (-26)7
-12v = -182
v = 182/12
v = 15 1/6
is the only acute angle whose sin = 1/2. Therefore, cos (
) =
