Question

Right triangle XYZ is shown below with the dimensions given in yards (yd).

Which is closest to the measure of ?

18.6 degree
70.3 degree
71.4 degree
19.7 degree

Answer 1

we know that

cos x=XZ/XY

XZ=28 yd

XY=83 yd

cos x=28/83

X=arc cos (28/83)---------> X=70.28°---------> X=70.3°

the answer is

X=70.3°
