Answer:
Each side of the L-shaped sidewalk is 126 m and 32m respectively.
Step-by-step explanation:
Given:
Total length of the sidewalk = 158 meters
Cutting across the lawn the distance = 130 meters
The L-shaped lawn will be treated as a right angled triangle.
So the 130 m distance is the hypotenuse here.
Let one side of the L-shaped lawn be 'x' meter so the another side will be (158-x) meters.
Applying Pythagoras formula.

So,
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
⇒
Applying quadratic formula;
Quadratic formula :
where a=1 and b=-158 and c=4032
So the value of x= 126 and 32.
The length of each side of the sidewalk is 'x'= 126 m and '(158-x)'='(158-126)'=32 m

Because You must do the original number by the new.
so, 425-340= 85
but ur not done now,
divide that 85 by the original number then times by 100!
85/340= .25*100= 25%
and ur done hope this helped

Answer:
(b) 5, 17
Step-by-step explanation:
You can try the answer choices easily enough.
2 +3×8 ≠ 14
2 +3×5 = 17 . . . . this choice works (5, 17)
2 +3×2 ≠ 20
2 +3×4 ≠ 18
2 +3×10 ≠ 12
__
Or, you can solve the equation:
x + (2 +3x) = 22
4x = 20 . . . . . . . . subtract 2
x = 5 . . . . . . . . . . divide by 4
The numbers are 5 and (22 -5) = 17.
Answer: b.not enough info
Step-by-step explanation:
Corresponding angles of congruent triangles are congruent, so 
However, we don't have all 3 interior angles of either triangle, so we cannot conclude anything.
