Determine the angle x in the triangle given below with AC = 2 and BC = 13.
( it is a right angles triangle: CB is the hypotenuse; AC is where C^AB is where the 90 degreee angle is and C^BA is x)

Question

Determine the angle x in the triangle given below with AC = 2 and BC = 13.
     ( it is  a right angles triangle: CB is the hypotenuse; AC is where C^AB is where the 90 degreee angle is  and C^BA is x)

easier to label triangles as angles A, B, C and opposite sides a, b, c respectively.

anonymous · Answer

sin(x)=2/13
and so find the inverse of sin over 2/13 for the angle x.

anonymous · Answer

find BA first  whichbappears to be the height if am not wrong
h=sqrt of 169(13^2)-4(2^2)
h=sqrt of 165
h is approximately 12.8452
cos theatre = adj/hyp
=cos inverse of 12.8452/13
cos-1 of 0.14563
=81.6 degrees

mathfrick: i think x can't be 81.6 degrees, because the side opssite to x is just 2 units in lenght.
