2nd is correct answer
Answer:
∠B
7(13)-1=90˚
Step-by-step explanation:
Are you saying ∠ABC or ABC as sides?
1. ∠ABC
(7x-1)+(4x+1)+(3x-2)=180˚
14x-2=180˚
14x=182
x=182/14
x=13˚
2. plug in
∠A
4(13)+1=53˚
∠B
7(13)-1=90˚
∠C
3(13)-2=37˚
Answer: width = 280 miles, length = 380 miles
<u>Step-by-step explanation:</u>
width: L - 100
length: L
Perimeter = 2(Length) + 2(width)
1320 = 2(L) + 2(L-100)
1320 = 2L + 2L - 200
1320 = 4L - 200
1520 = 4L
380 = L
width: L - 100 ---> 380 - 100 = 280
length: L ---> 380
