The answer to your question is 6.08 cm

Step-by-step explanation:

Start with the green triangle

hypotenuse = 8 / cos 35

hypotenuse = 9.77

Yellow triangle hypotenuse

hypotenuse = (9.77 - 2.5) + 3.6

= 6.2 cm

adjacent side = 6.2 x cos 14

= 6 cm

Hypotenuse of the pink triangle

hypotenuse = (6 - 2.1) + 2.9

= 3.9 + 2.9

= 6.8 cm

Angle of the pink triangle

sin Ф = 3.8 / 6.8

= 0.56

Ф = 34°

Adjacent side of the pink triangle

Adjacent side = 6.8 x cos 34

Adjacent side = 5.6 cm

Adjacent side of the blue triangle

Adjacent side = 5.6 - 3.2

= 2.4 cm

Opposite side of the blue triangle

Opposite side = 2.4 x tan 42

Opposite side = 2.1 cm

Hypotenuse of the white triangle

hypotenuse = 2.1 / sin 37

hypotenuse = 3.5 cm

Hypotenuse of the yellow triangle

hypotenuse = 4.08 + 3.5

hypotenuse = 7.6 cm

Opposite side of the big yellow triangle

Opposite side = 7.6 x sin 57

Opposite side = 6.4 cm

Adjacent side of the small white triangle

Adjacent side = 6.4 - 2.2

= 4.2 cm

Hypotenuse of the small white triangle

Hypotenuse² = 1.7² + 4.2²

Hypotenuse² = 2.89 + 17.64

Hypotenuse = 4.53 cm

Hypotenuse of the first pink triangle

Hypotenuse = 4.53/ cos 20

= 4.82 cm

Hypotenuse of the second pink triangle

Hypotenuse = 4.82 + 1.5

= 6.32 cm

Opposite side of the second pink triangle

Opposite side = 6.32 x sin 74

= 6.08 cm

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3) so

(x^2-9)/ (x + 3) = x-3
