Answer:

x≈12.5

Step-by-step explanation:

angle a=90°,angle b=28°,side c=11

a+b+Y=180°

Using

y=62°

Using the law of sines, we calculate unknown side x

c=11, a/c=sin a°/sin y°

a=c*sin a°/sin y°

a=11*sin 90°/sin 62°=12.46

12.46≈12.5

Answer is 12.5

Cos 28 = 11/x

X= 11/cos 28

X= 11/0.8829

X= 12.4589=~ 12.5
