<h2>The value of x "option A) 12.5" is required answer.</h2>
Step-by-step explanation:
In given figure,
Base (b) = 11 and Angle = 28°
To find, the value of x = ?
We know that,
Where, h is the hypotaneous = x
⇒
⇒
The value of = 0.8829
⇒ x =
⇒ x = 12.458
⇒ x ≈ 12.5
∴ The value of x ≈ 12.5
Thus, the value of x "option A) 12.5" is required answer.
