Question

Pleasse help now and show all work thanks so much

Answer 1

X = 11 cos 22
x = 10.20

Answer 2

Ok its been a while since ive done this but all ur doing is plugging in values then multiplying.
So itd be-

cos(22)=x/11
 then multiply both sides by 11x cos(22)=x
next is cos(22)=x/11
then 11cos(22)=x
x=10.199 which rounds to 10.2
