Question

Solve for x. Round your answer to the nearest whole number.

Answer 1

Answer:

C. x=12

Step-by-step explanation:

imagine a circle with is center being the corner with the 40 degree angle. and a radius of 19.

and now turn the picture by 90 degrees or 270 degrees (not important, this would be just to visualize things better).

x is actually sine of the 40 degree angle multiplied by the radius (19).

x = sin(40)×19 = 12 (12.21296...)
