draw the right triangle
call the vertical leg "a" and call the horizontal leg "b"
one angle is 53º, one angle is 90º, and the third angle is 90-53=37º
sin53=a/45
0.7986=a/45
a=45(0.7986)
a=35.937
cos53=b/45
0.6018=b/45
b=45(0.6018)
b=27.081
now you have all the angles and all the sides; choose which one you need
