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$\; 48.2^{\circ}$

Solve the equation using the distributive property and properties ofequally 1/2 (x+6)=18 what is the value of X

Natali [406]

x = 30

The distributive property says that we need to multiply what's in the brackets by 1/2 (so 1/2*x and 1/2*6) to get the equation 1/2x + 3 = 18.

Then we need to subtract our constant, 3, from boths sides to get 1/2x = 15.

Multiply both sides by two to isolate x and you get x = 30.

Hope this helps! :)
