If t = 18 and r = 12, find S. Round to the nearest tenth.

choli [55]

Answer: <em>S</em> ≈ 48.2°

Step-by-step explanation:

We can use trigonometry functions to solve.

Looking at angle <em>S</em>, t = 18 is the hypotenuse and r = 12 is the adjacent side. This means we can use the cosine function.

$\displaystyle cos(S) = \frac{\text{adjacent side}}{\text{hypotenuse }}=\frac{12}{18}$

$\displaystyle cos^{-1} (cos(S)) = (\frac{\text{adjacent side}}{\text{hypotenuse }}=\frac{12}{18})cos^{-1}$

$S = 48.189685...\\S \;$\approx$\; 48.2^{\circ}$

8x - 9 - 5x = 3x - 36 - 18x

makkiz [27]

Answer:

$8x - 9 - 5x = 3x - 36 - 18x \\ 8x - 5x - 9 = 3x - 18x - 36 \\ 3x - 9 = - 15x - 36 \\ 3x = - 15x - 36 + 9 \\ 3x = - 15x - 27 \\ 3x + - 15x = - 27 \\ - 12x = - 27 \\ x = \frac{ 27}{12}$
