For the given triangle, x = 16 units.
Step-by-step explanation:
Step 1:
In the given triangle, the angle is 60°. The adjacent side has a length of 8 units while the hypotenuse of the triangle measures x units. To calculate the cos of angle A we divide the length of the adjacent side by the length of the hypotenuse.
cos A
Step 2:
The length of the adjacent side = 8 units.
The length of the hypotenuse = x units.
So the hypotenuse of the given triangle measures 16 units. x = 16 units which is the third option.
