Name the adjacent side
of ∠C

Slide 4 - Quiz

Name the mnemonic you learned last week

Slide 5 - Open question

Calculate ∠P

Slide 6 - Slide

Calculate ∠P

cos (θ) = \frac{​ a ​ ​}{​ h ​}

Slide 7 - Slide

Calculate ∠P

cos (∠ P) = \frac{​ 6 . 2 ​ ​}{​ 8 . 3 ​}

cos (θ) = \frac{​ a ​ ​}{​ h ​}

Slide 8 - Slide

Calculate ∠P

cos (∠ P) = \frac{​ 6 . 2 ​ ​}{​ 8 . 3 ​}

∠ P = cos^{​ - 1 ​ ​} (\frac{​ 6 . 2 ​ ​}{​ 8 . 3 ​})

cos (θ) = \frac{​ a ​ ​}{​ h ​}

Slide 9 - Slide

Calculate ∠P

cos (θ) = \frac{​ a ​ ​}{​ h ​}

cos (∠ P) = \frac{​ 6 . 2 ​ ​}{​ 8 . 3 ​}

∠ P = cos^{​ - 1 ​ ​} (\frac{​ 6 . 2 ​ ​}{​ 8 . 3 ​})

∠ P \approx 41.67

Slide 10 - Slide

Calculate KM

cos (66) = \frac{​ K M ​ ​}{​ 1 9 ​}

0.406 . . . = \frac{​ K M ​ ​}{​ 1 9 ​}

K M = 0.406 . . . \cdot 19

K M \approx 7.73

cos (θ) = \frac{​ a ​ ​}{​ h ​}

Slide 15 - Slide

Calculate FG

0.74 . . . = \frac{​ 7 ​ ​}{​ F G ​}

F G = \frac{​ 7 ​ ​}{​ 0 . 7 4 . . . ​}

F G \approx 9.42

sin (48) = \frac{​ 7 ​ ​}{​ F G ​}

sin (θ) = \frac{​ o ​ ​}{​ h ​}
