$\huge\boxed{D)\ 0.7241}$

Step-by-step explanation:

$cosine=\dfrac{adjacent}{hypotenuse}\\\\\text{We have}:\\\\adjacent=21,\ hypotenuse=29\\\\\text{Substitute:}\\\\\cos X=\dfrac{21}{29}=21:29\approx0.7241$

height = 26 cm

Step-by-step explanation:

The area (A) of a triangle is calculated using the formula

A = $\frac{1}{2}$ bh ( b is the base and h the height )

here b = 38 and A = 494, hence

494 = 0.5 × 38 × h

494 = 19h ( divide both sides by 19 )

26 = h

The height of the triangle is 26 cm
