Answer:

Answer B (57 degrees) is closest

Step-by-step explanation:

Find the measure of Angle A, if the hypotenuse is 26 and the horizontal leg is 14.  If this is true, then

cos A = adj / hyp = 14/26 = 0.5385, and

Angle A = arccos 0.5385, which (via calculator) comes out as 1.002 radian, or 57.421 degrees.  Answer B (57 degrees) is closest.

Answer: B

Step-by-step explanation:

cos X = adjacent / hypotenuse

cos A = 14/26

cos A = 0.54

A = cos^(-1) 0.54

A = 57°
