Answer:
Step-by-step explanation:
Use the fact that sin 30 =0.5 and cos 30 = sqrt 3/2
we have answers as
8. u=16 and v = 
9) y=5 and x=
10) tan 30 =
So y=
x=
11) a=22 and b=11
12) b=1.5 and a=
13) y=
and x=10
Answer:
The other side is 7.48 yards.
Step-by-step explanation:
Given that,
Hypotenuse = 15 yards
One leg = 13 yards
We need to find the length of the other leg. We can use the Pythagoras theorem to find it such that,

Where
h is other leg
Put all the values,

So, the other side is 7.48 yards.
Solve for x by simplifying both sides of the equation, then isolating the variable.
x = 4
