Answer: millas
Step-by-step explanation: solo en una milla hay 1.609 kilómetros so 20 millas es mayor que 20 kilómetros.
Lo siento si está no es la respuesta que busca.
Perimeter = A + B + C
shortest side = a
second side = 2a
Third side = 3a
P = 6a
P=2T
P is twice the length of the longest side
Answer:
Step-by-step explanation:
Consider the figure as the difference of a trapezoid and a rectangle.
<u>Area of the trapezoid:</u>
- a = 3 - (-2) = 5 units
- b = 9 - (-6) = 15 units
- h = 5 - (-5) = 10 units
- A = (a + b)h/2 = (5 + 15)(10)/2 = 100 square units
<u>Area of the rectangle:</u>
- l = 5 - (-2) = 7 units
- w = -1 - (-5) = 4 units
- A = lw = 4*7 = 28 square units
<u>Area of the figure:</u>
- 100 - 28 = 72 square units
Answer:
Option (3) and (4) are correct .
w║n and n⊥m and w║n so w⊥m
Step-by-step explanation:
In the given figure, we have a set of lines which are parallel and perpendicular.
Parallel lines are lines in same plane which when extended do not meet and are always same distance apart from each other.
Perpendicular lines are two non-vertical lines in the same plane intersect at right angles.
From the figure given,
w║n and n⊥m as angle between a and n is right angle that is ∠mxn = 90° (given)
Since, w║n so w⊥m also both w and n shows same property as both are parallel lines.
Thus, option (3) and (4) are correct .
