Question 1132720
A ladder leaning against a house makes an angle of 60 degrees with the ground. The foot of the ladder is 7 feet from the house. How long is the ladder?
<pre>The length of the hypotenuse of a 30-60-90 special triangle is TWICE the length of the SHORTER leg, and 
since the shorter leg (7 feet) is opposite the SMALLER angle (30<sup>o</sup>), the hypotenuse becomes: 2(7), or {{{highlight_green(matrix(1,2, 14, feet))}}}
