Answer:
a. rational - It can be written as a fraction so it's rational.
b. rational - Simplified it equals to 9, a whole, therefore rational, number.
c. irrational - Even once simplified, it contains a square root, therefore it's irrational.
d. rational - It can be written as a fraction so it's rational.
e. irrational - It cannot be simplified from a square root, therefore it's irrational.

Answer:
The answer is 68°
Step-by-step explanation:
<h3>
<u>Given</u>;</h3>
- A right angled-triangle IGH.
- where, m∠G = 90°
<h3><u>To </u><u>Find</u>;</h3>
We know that
tan θ = Opp ÷ Adj
tan θ = 5 ÷ 2
tan θ = 2.5
tan θ = 68.2 ≈ 68
We know that tan 68 = 2.5
Thus, The m∠I is 68°
