Answer:
x = 5, supplementary
Step-by-step explanation:
6x + 13 + 14x - 33 = 180
20x - 20 = 80
20x = 100
x = 5
Answer:
8.87
Step-by-step explanation:
The square means "right angle"
![\sin(\alpha ) = \frac{x}{13} \\ \\ \sin(43) = \frac{ x }{13} \\ \\ x = \sin(43) \times 13 \\ x = 8.86597868081 \\ x = 8.87](https://tex.z-dn.net/?f=%20%5Csin%28%5Calpha%20%29%20%20%3D%20%20%5Cfrac%7Bx%7D%7B13%7D%20%20%5C%5C%20%20%5C%5C%20%20%5Csin%2843%29%20%20%3D%20%20%5Cfrac%7B%20x%20%7D%7B13%7D%20%20%5C%5C%20%20%5C%5C%20x%20%3D%20%20%5Csin%2843%29%20%20%5Ctimes%2013%20%5C%5C%20x%20%3D%208.86597868081%20%5C%5C%20x%20%3D%208.87)
Area equals three time the square root of three all of this divided by 2 times the length of the side squared. So this would be 1039.23mi^2
