Question 713203
 The hypotenuse of a right triangle is 26cm, and the length of one leg is 10cm.
 Find, to the nearest degree, the measure of the smallest angle of the triangle.
:
Find the measure of the angle enclosed by the hypotenuse and the 10 cm leg
Use the cosine; side adj/hypot
cos(A) = {{{10/26}}}
A = 67 degrees,  
Find the smallest angle: 180 - 90 - 67 = 23 degrees
