Question 206120
In a right triangle the hypotenuse is labeled B. The second longest side is labeled A and the shortest is 3. the angle between side B and 3 is 72 degrees. B= ? and A = ?
---------------------------
Draw the picture
tan(72) = A/3
A = 3*tan72
A = 9.233
----------------
cos(72) = 3/B
B = 3/cos(72)
B = 9.708
