Answer:

Second Option

[tex]a=1.46[/tex]

Step-by-step explanation:

The triangle of the figure is a straight triangle.

We know the length of the hypotenuse, h = 2, and we know the angle A = 43°. We need to find the length a. Side a is the side adjacent to the 43° angle

By definition we know that

[tex]cosx = \frac{adjacent}{hypotenuse}[/tex]

Then

adjacent = a

hypotenuse  =2

x =43°

[tex]cos(43\°) = \frac{a}{2}[/tex]

[tex]a= 2cos(43\°)[/tex]

[tex]a= 1.46[/tex]
