Answer:

∠x = 63°

Step-by-step explanation:

The exterior angle added with the measure of ∠BAC will equal 180, since they will form a straight line, so we can calculate the measure of ∠BAC:

128 + x = 180

x = 52

∠BAC = 52°

The angles in a triangle all add up to 180°, so we can set up another equation to find x:

52 + 65 + x = 180

117 + x = 180

∠x = 63°

Answer:

Length in feet is equal to $\frac{2P}{6.5}$ , where P is the perimeter

Step-by-step explanation:

Let the width (W) of the yard be "X"

$W = w$

Then the length(L) of the yard will be

$2\frac{1}{4} * w$

$L = \frac{9}{4} *w$

The perimeter of the yard will be equal to the sum of twice the length and width of the yard

Thus,

$P = 2 W + 2L\\$

Substituting the given values in above equation, we get -

$P = 2 w + 2 (\frac{9}{4})w\\P = 2w + 4.5 w\\P = 6.5w$

Thus, width in terms of perimeter is equal to

$w = \frac{P}{6.5}$

Length in feet is equal to $\frac{2P}{6.5}$
