Answer: 5.6
===================================
Work Shown:
cos(angle) = adjacent/hypotenuse
cos(B) = AB/BC
cos(62) = AB/12
12*cos(62) = AB
AB = 12*cos(62)
AB = 5.63365875
AB = 5.6

Answer:
a = 4.949
b = 4.949
c = 7
Step-by-step explanation:
c ( hypothenuse ) = 7
to find a, use sine
Sine = 
Sine 45 = 
sine of 45 is 0.707
0.707 = 
multiplt 7 on both sides:
0.707 x 7 =  x 7
 x 7 
a = 4.949
to find b, use cosine
Cosine = 
Cos 45 = 
cos of 45 is 0.707
0.707 = 
multiply 7 on both sides:
0.707 x 7 =  x 7
 x 7 
b = 4.949
