The length, l, of a steel rod is 7.3 m, correct to 1 decimal place.
complete the error interval for length l.

  [7.25, 7.35)

Step-by-step explanation:

The least significant digit is in the tenths place. The error can be as much as half of one tenth, or 0.05.

The lower bound is ...

  7.3 - 0.05 = 7.25 . . . . . error subtracted from value

The upper bound is ...

  7.3 + 0.05 = 7.35 . . . . . error added to value

Since 7.35 is rounded up to 7.4, the maximum value of L must be less than that.

  7.25 ≤ L < 7.35 . . . meters

In many cases, the upper bound on L is taken to be exactly 7.35. For all practical purposes it is. If you're asked for upper and lower limits, you'd have to say they are 7.35 and 7.25 m, respectively.

Let’s say the side BC is extended till D

1) measure of angle ACD = 105° ( angle ACD is exterior angle)
45 + 60 = 105
2) I found the answer by adding the values of Angle A and Angle B or by using the exterior angle property.
3) I observed that exterior angle property can be used here. Exterior angle property is that an exterior angle of a triangle is equal to the sum of the opposite interior angles.
