Answer:
86 yd
Step-by-step explanation:
the area of the shaded region is 2924 yd²
let b the doted side next y :
the area of the total triangle is :
A = (y+b)*68/2 = 2924+ b*68/2
- [tex]\frac{(y+b)*68}{2}[/tex] = [tex]\frac{b*68}{2}[/tex] + 2924
- [tex]\frac{68*(y+b-b)}{2}[/tex] = 2924
- 68*y/2 = 2924
- 68y = 2*2924
- y= (2*2924)/68
- y= 86 yd
