70=A=Lw
L=2w-4
70=(2w-4)w
70=2w²-4w
70=2(w²-2w)
35=w²-2w
0=w²-2w-35
0=(w+7)(w-5)
-7=w or w=5
Measurements aren't negative
w=5 ft
L=2(5)-4
L=6 ft
Answer:
24
Step-by-step explanation:
XW=WY=12
If the opposite angle is 30, the hypotenuse is double the small side.
XZ=XW=2·12=24
17/5
23=5x+6
23-6=5x
17=5x
X=17/5
12
