Round to 2 decimal places

Slide 4 - Open vraag

Calculate ∠F

Round to 2 decimal places

Slide 5 - Tekstslide

Calculate KM

Slide 6 - Tekstslide

Calculate KM

cos (θ) = \frac{​ a ​ ​}{​ h ​}

Slide 7 - Tekstslide

Calculate KM

cos (66) = \frac{​ K M ​ ​}{​ 1 9 ​}

cos (θ) = \frac{​ a ​ ​}{​ h ​}

Slide 8 - Tekstslide

Calculate KM

cos (66) = \frac{​ K M ​ ​}{​ 1 9 ​}

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

cos (θ) = \frac{​ a ​ ​}{​ h ​}

Slide 9 - Tekstslide

Calculate KM

cos (66) = \frac{​ K M ​ ​}{​ 1 9 ​}

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

K M = 0.406 . . . \cdot 19

cos (θ) = \frac{​ a ​ ​}{​ h ​}

Slide 10 - Tekstslide

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 11 - Tekstslide

Calculate FG

Slide 12 - Tekstslide

Calculate FG

sin (θ) = \frac{​ o ​ ​}{​ h ​}

Slide 13 - Tekstslide

Calculate FG

sin (48) = \frac{​ 7 ​ ​}{​ F G ​}

sin (θ) = \frac{​ o ​ ​}{​ h ​}

Slide 14 - Tekstslide

Calculate FG

0.74 . . . = \frac{​ 7 ​ ​}{​ F G ​}

sin (48) = \frac{​ 7 ​ ​}{​ F G ​}

sin (θ) = \frac{​ o ​ ​}{​ h ​}

Slide 15 - Tekstslide

Calculate FG

0.74 . . . = \frac{​ 7 ​ ​}{​ F G ​}

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

sin (48) = \frac{​ 7 ​ ​}{​ F G ​}

sin (θ) = \frac{​ o ​ ​}{​ h ​}

Slide 16 - Tekstslide

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 ​}
