Solve each triangle: Find all the missing sides and angles. Round answers to the nearest tenth.

horrorfan [7]

Step-by-step explanation:

$let \: angle \: be \: \alpha \\ \tan( \alpha ) = \frac{p}{b} \\ \tan(69.9) = \frac{9.7}{bc} \\ bc = \frac{9.7}{2.73} \\ bc = 3.55 \\ by \: using \: pythagorean \: theorem \\ ab = \sqrt{ {9.7}^{2} } + {2.73}^{2} \\ ab = 10.07$

59 and/or 60. Determine if the triangles are similar. If they are similar, find the scale factor from ABC to JKL.

Answer:

59) not similar

60)

Step-by-step explanation:

59) The ratios of the side lengths shown cannot be reduced. They are different, so the triangles are not similar.

7:8:12 ≠ 6:7:11

60) The side length ratios both reduce to 8:7:10, so the triangles are similar.

∆ABC ~ ∆JKL

The scale factor is LJ/CA = 25/20 = 5/4. (Multiplying ABC by 5/4 will give JKL.)
