Which interior angle measurements construct an acute triangle? 1. 71°, 32°, 77°
2. 54°, 67°, 89°
3. 103°, 66°, 11°
4. 12°, 27°, 57°

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
