Answer:
∠ CDA = 32.3°
Step-by-step explanation:
See the given figure attached to this answer.
Draw perpendiculars from B and C on AD which is BE and CF.
Now, Δ ABE is a right triangle and AE² = AB² - BE² = 7.5² - 6² = 20.25
⇒ AE = 4.5 cm
Now, DF = AD - EF - AE = 24 - 10 - 4.5 = 9.5 cm {Since BC = EF}
And CF = BE = 6 cm.
Now, Δ CFD is a right triangle and
{Where β = ∠ CDA}
⇒
Degree.
So, ∠ CDA = 32.3° {Correct to one decimal place} (Answer)

Answer:
The answer is 2.5135145
Step-by-step explanation:
- The irrational number between 5,25 and 5,26
- 2.5135145...
- The number is non-terminating and non-recurring. Hence, it is an irrational number.
- A real number that cannot be expressed as a simple fraction is called an irrational number.
- It is impossible to express in terms of a ratio.
- If N is irrational, it is not equal to p/q, where p and q are integers and q is not equal to 0.
- Example: √2, √3, √5, √11, √21, π(Pi) are all irrational.
