This is something you'll need a T table for, or a calculator that can compute critical T values. Either way, we have n = 10 as our sample size, so df = n-1 = 10-1 = 9 is the degrees of freedom.
If you use a table, look at the row that starts with df = 9. Then look at the column that is labeled "95% confidence"
I show an example below of what I mean.
In that diagram, the row and column mentioned intersect at 2.262 (which is approximate). This value then rounds to 2.26
<h3>Answer: 2.26</h3>
Answer:
Therefore the value of tangent of ∠ is
°.
Step-by-step explanation:
Given that,
In Δ, ∠
°,
and
and we have to find the value of tangent of ∠
Diagram of the given triangle is shown below:
Now,
Δ is a right angle triangle, so we can use all the trigonometric ratio.
=
tangent of ∠ =
=
=
=
∴∠ =
= ° ≅
°
Therefore the value of tangent of ∠ is
°.
