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