Answer:
|96.55−0.02|= x
|96.55+0.02|=x
Step-by-step explanation:
Given that:
Measured length of beam = 96.55 cm
Measurement accuracy = plus or minus (± 0.02cm)
Limits of actual length of the beam:
Let limit of actual length = x
Lower limit :
|measured length - accuracy| = x
|96.55 - 0.02| = x
96.53) x
Upper limit :
|measured length + accuracy| = x
|96.55 + 0.02| = x
96.57 = x
Answer:
Width = 5
Length = 10
Step-by-step explanation:
Let x be the width of the rectangle
2x + 2(2x) = 30
x = 5
Width = 5
Length = 10
Given:
In triangle XYZ, J, K and L are midpoints of the sides.
JK = 38, XZ = 96, YX = 56.
To find:
KL, YZ and LZ.
Solution:
We have, J, K and L are midpoints of the sides of triangle XYZ.
JK = 38, XZ = 96, YX = 56.
Midsegment theorem: If a line segment between the midpoints of two sides of the triangle, then the length of the segment is half of the third side.
Using midsegment theorem, we get
And,
L is the midpoint of the side YZ. So,
Therefore, the measures of KL, YZ and LZ are 28, 76 and 38 respectively.
THANKS FOR THE 5 POINTS I need it but I will give you answer is 5 2 3 1
