Answer:
.
Step-by-step explanation:
It is given that a number, x, rounded to 2 significant figures is 1300.
It is possible if,
1. The value of x is greater than of equal to 1250 and less than or equal to 1300.
i.e., ...(1)
2. The value of x is greater than of equal to 1300 and less than 1350.
i.e., ...(2)
On combining (1) and (2), we get
1350 is not included in the error interval for x.
Interval notation is .
Therefore, the error interval for x is .

Step-by-step explanation:
To find x use the sine ratio in the right triangle and the exact value
sin60° = , then
sin60° = =
=
( cross- multiply )
x = 28
( divide both sides by
)
x = 28
-----------------------------------------------------------
To find y use the tangent ratio in the right triangle and the exact value
tan60° = , then
tan60° = =
=
( multiply both sides by y )
14 = y
( divide both sides by
)
y = 14
