Square = identical sides.
therefore, 125miles^2 = (square root 125)^2
square root 125 = 11.18033989miles
Answer:
2x + 4y = 12 and y = -1/2x + 3
Answer:
I believe that the answer is 13 degrees.
Step-by-step explanation:
Let's call the angle opposite 85 degrees y. y must be 85 degrees as vertically opposite angles must be equal.Let's call the third angle of the triangle which contains x, z. The angle next to z must be 98 degrees, as the rule of corresponding angles proves this if you look at the 98 degrees at the bottom of the digram, helping us find that angle z is 82, as angles on a straight line add to 180, so 180-98 is 82. y+z+x=180. We can simplify this now to 85 degrees+82 degrees+x is 180 degrees. 85 plus 82 is 167, and 180-167 is 13, so x is 13 degrees.
Let the length be l
Then,
l *(l-3)= 88
l²-3l =88
l²-3l-88=0
l²-11l +8l -88 =0
l(l-11) + 8(l-11) =0
(l+8)(l-11)=0
As, l can't be negative, length=11cm and width=(l-3)=11-3 =8 cm
