Answer:
x = 14.55
Step-by-step explanation:
Given that,
The hypotenuse of the triangle, H = 19
Angle, [tex]\theta=40^{\circ}[/tex]
We need to find the value of x. We can use trigonometry to find it such that,
[tex]\cos\theta=\dfrac{B}{H}[/tex]
Where
B is base and H is Hypotenuse
We have, B = x and H = 19
So,
[tex]\cos(40)=\dfrac{x}{19}\\\\x=19\times \cos(40)\\\\x=14.55[/tex]
So, the value of x is equal to 14.55.
