The perimeter without the diagonal is 4*120 = 480
That covers the outside of the field
The diagonal is 120 *

= 169.7 yd

Answer:
i don't know
Step-by-step explanation:
The measure of ∠C is 54°.
<h3>To solve the problem :</h3>
let us assume that line n is a mirror.
∴ ∠A = ∠A' = 59°
∠B = ∠B' = 67°
∠C = ∠C'
According to property of triangles :
Sum of all angles of a triangle is 180°.
∴ A + B + C = 180°
59 + 67 + C = 180
C = 
C = 54°
<h3>∴ The measure of ∠C is 54°.</h3>
