Question 566077
solve for y and z
round values to the nearest whole number.
a right triangle.
the side across the right angle 13 
the length across the acute or the smallest angle "y" equals 5
and the other angle is z
------------
It's the 5, 12, 13 right triangle.
------
The smallest angle is opposite the side of 5.
Its sine = 5/13
--> angle =~ 22.62 degs
The other angle is 90 - 22.62 = 67.38 degs
