Answer:25 ft
Step-by-step explanation:
This triangle is an isosceles triangle (2 sides are congruent), we see this because is two angles of a triangle is congruent, then the two opposite sides are congruent.
From this information, we can say that 2x-1 = x+4
Add 1 on both sides to get 2x=x+5
Then minus x on both sides to get x=5
Next, plus x into the two equations separately.
1) 2 times 5-1
2 times 5 is 10
10-1=9
2) 5+4=9
Finally, add the sides together to get the answer.
9+9+7=25ft
Hope this helped!
