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
why not just ask the question here instead? :)
Answer:
∠E = ∠F = 41°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 given angles and equate to 180
x + x + 98 = 180 ( subtract 98 from both sides )
2x = 82 ( divide both sides by 2 )
x = 41
Hence
∠E = ∠F = 41°
